RELEASED TO: The Greeley Tribune on PUBLISHED: October 1, 2010 September 27, 2010 COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT AIR POLLUTION CONTROL DIVISION OPERATING PERMIT RENEWAL SUMMARY PERMIT NUMBER: 95OPWE001 AIRS ID#: 1230126 DATE: September 27, 2010 APPLICANT: Thermo Power and Electric LLC—Greeley REVIEW ENGINEER: Jacqueline Joyce SOURCE DESCRIPTION Thermo Power and Electric LLC has applied for renewal of their Operating Permit issued for the Greeley facility located at 510 18th Street in Greeley Colorado on the University of Northern Colorado campus in Weld County. This facility consists of two combustion turbines used to generate steam and produce electricity for sale and is classified under SIC 4931. This facility is located in an area classified as attainment/maintenance for carbon monoxide (CO). Under that classification, all SIP-approved requirements for CO will continue to apply in order to prevent backsliding under the provisions of Section 1100) of the Federal Clean Air Act. This area is classified as non-attainment for ozone and is part of the 8-hr Ozone Control Area as defined in Regulation No. 7, Section II.A.1. This source is a major stationary source with respect to Prevention of Significant Deterioration (PSD) review and non-attainment area new source review(NANSR)requirements. Wyoming, an affected state is within 50 miles of this facility. Rocky Mountain National Park, a Federal Class I designated area, is within 100 km of this facility. This source is not subject to the Accidental Release provisions of section 112(r) of the Federal Clean Air Act. In addition, although the combustion turbines are equipped with steam injection to control NOx emissions they are exempt from the compliance assurance monitoring (CAM) requirements in 40 CFR Part 64 because at the time the CAM plan was required the Title V permit specified a continuous compliance determination method (§ 64.2(b)(1)(vi)).

EMISSION SOURCES The following discussion identifies the changes that were made in the renewal permit. Combustion Turbines— Based on EPA's response to a petition on another Title V permit, minor language changes were made to various permit conditions to clarify that only natural gas is used for permit conditions that rely on fuel restriction for the compliance demonstration. The frequency for performance testing was revised to every five years (affects both Section II, Conditions 1 (combustion turbines) and 3 (performance test requirements)). Portable Monitoring Requirements—The portable monitoring language was revised to reflect the most recent version. Emergency Generator and Emergency Fire Water Pump Engine-The diesel fired engines driving an emergency generator and an emergency fire water pump had previously been included in the insignificant activity list in Appendix A of the permit. However due to recent revisions to the requirements in 40 CFR Part 63 Subpart ZZZZ (National Performance Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines) these engines are now subject to requirements in 40 CFR Part 63 Subpart ZZZZ and can no longer be considered insignificant activities. The engines must comply with work practice standards in 40 CFR Part 63 Subpart ZZZZ beginning May 3, 2013. The engines and the appropriate applicable requirements for these engines have been included in Section 11.5 of the permit. ALTERNATIVE OPERATING SCENARIOS The alternative operating scenario (AOS)was revised to reflect the most recent version. INSIGNIFICANT ACTIVITY LIST The emergency generator and emergency fire water pump engines were removed from the insignificant activity list. They are now included in Section II of the permit. PERMIT SHIELD No additional non-applicable requirements were included in the permit shield. TECHNICAL REVIEW DOCUMENT For RENEWAL of OPERATING PERMIT 95OPWE001 Thermo Power and Electric LLC — Greeley Facility Weld County Source ID 1230126 Prepared by Jacqueline Joyce June 2010 Revised September 2010 I. Purpose: This document will establish the basis for decisions made regarding the applicable requirements, emission factors, monitoring plan and compliance status of emission units covered by the renewed operating permit proposed for this site. The current Operating Permit was issued January 1, 2006. The expiration date for the permit is January 1, 2011. This document is designed for reference during the review of the proposed permit by the EPA, the public, and other interested parties. The conclusions made in this report are based on information provided in the renewal application submitted August 10, 2009, comments on the draft permit and technical review document received on September 8, 2010, previous inspection reports and various e-mail correspondence, as well as telephone conversations with the applicant. Please note that copies of the Technical Review Document for the original permit and any Technical Review Documents associated with subsequent modifications of the original Operating Permit may be found in the Division files as well as on the Division website at http://www.cdphe.state.co.us/apiTitlev.html. Any revisions made to the underlying construction permits associated with this facility made in conjunction with the processing of this operating permit application have been reviewed in accordance with the requirements of Regulation No. 3, Part B, Construction Permits, and have been found to meet all applicable substantive and procedural requirements. This operating permit incorporates and shall be considered to be a combined construction/operating permit for any such revision, and the permittee shall be allowed to operate under the revised conditions upon issuance of this operating permit without applying for a revision to this permit or for an additional or revised construction permit. II. Description of Source This facility consists of a cogeneration facility defined under Standard Industrial Classification 4931. Electricity for sale is produced by two (2) combustion turbines and a steam turbine. Each combustion turbine serves a generator rated at 42.5 MW (name- plate) and the steam turbine generator is rated at 16.3 MW (name-plate). Page 1 The facility is located at 510 18th Street, in Greeley, CO on the University of Northern Colorado (UNC) Campus. This facility is located in an area classified as attainment/maintenance for carbon monoxide (CO). Under that classification, all SIP- approved requirements for CO will continue to apply in order to prevent backsliding under the provisions of Section 110(1) of the Federal Clean Air Act. This Area is classified as non-attainment for ozone and is part of the 8-hr Ozone Control Area as defined in Regulation No. 7, Section II.A.1. Wyoming, an affected state, is within 50 miles of the facility. Rocky Mountain National Park, a federal Class I area is within 100 km of this facility. Based on the information provided in the renewal application, no changes have been made to any of the significant emission units. The summary of emissions that was presented in the Technical Review Document (TRD) for the renewal permit has been reproduced here. Since there have been no changes to permitted emission and/or fuel consumption limitations and no new emission units have been added to the facility, the potential to emit (PTE) has not changed. Both potential and actual emissions (in tons per year) at the facility are as follows: Potential to Emit(tons/yr) Emission Unit PM PM10 SO2 NOx CO VOC HAPS Turbine (T001) 20.8 20.8 10 535.5 45 6.24 See Table Turbine (T002) 20.8 20.8 10 535.5 45 6.24 on Page 8 Total 41.6 51.6 20 1,071. 90 12.48 5.2 Actual Emissions (tons/yr) Emission Unit PM PM10 SO2 NOx CO VOC HAPS* Turbine (T001) 3.4 3.4 1.6 88.2 7.4 1.0 0.16 Turbine (T002) 3.7 3.7 1.8 95.9 8.1 1.1 0.17 Total 7.1 7.1 3.4 184.1 15.5 2.1 0.33 *only formaldehyde emissions were above the APEN de minimis level. The criteria pollutant PTE shown above is based on permitted emission limits for the turbines. Note that there are no permitted emission limits for PMio for the turbines, PM10 is presumed to equal PM. Actual emissions are based on the information provided in the APENs included in a letter dated May 16, 2006 (2005 data). The breakdown of HAP emissions by emission unit and individual HAP is provided on page 8 of this document. The PTE of HAP emissions is based on emission factors (formaldehyde from AP-42 and others from the 8/22/03 EPA memo for turbines), permitted fuel consumption limits and a natural gas heat value of 1020 Btu/SCF. Page 2 MACT Requirements Although the facility is not a major source for HAPS, the EPA has been promulgating rules for area sources (sources that are not major), those requirements that could potentially apply to this facility are discussed below: Paint Stripping and Miscellaneous Surface Coating at Area Sources (40 CFR Part 63 Subpart HHHHHH) The final rules for paint stripping and miscellaneous surface coating were published in the Federal Register on January 9, 2008 and apply to area sources that perform paint stripping operations using methylene chloride, spray application of coatings to motor vehicles and mobile equipment and spray application of coatings that contain the target HAPS (chromium, lead, manganese, nickel or cadmium). As indicated in 40 CFR Part 63 § 63.11170(a)(2) and (3), spray applications (to motor vehicles and using coatings that contain the target HAPS) that meet the definition of facility maintenance are not subject to the requirements in this rule. The Division considers that any spray coatings of motor vehicles and mobile equipment and spray application of coatings that contain the target HAP at this facility would meet the definition of facility maintenance. The source indicated that none of the paint stripping chemicals used at the facility contain methylene chloride; therefore, the provisions in 40 CFR Part 63 Subpart HHHHHH do not apply. Reciprocating Internal Combustion Engines (RICE) (40 CFR Part 63 Subpart ZZZZ) Final revisions to the RICE MACT were published in the Federal Register on March 3, 2010 and these revisions address existing (commenced construction prior to June 12, 2006) compression ignition engines at area sources. The insignificant activity list indicates that there are diesel-fired engines driving a generator and a fire pump at the facility. Both engines are considered emergency engines. Since these engines were in the January 1, 2006 Title V renewal permit, these engines are existing engines and are subject to requirements in MACT ZZZZ. Since these engines are considered emergency engines they are subject to management standards (oil and filter change and inspect air cleaners, hoses and belts). The source is required to comply with these requirements by May 3, 2013. The appropriate applicable requirements will be included in the renewal permit. Compliance Assurance Monitoring (CAM) Applicability CAM was reviewed for these units during the first renewal (issued January 1, 2006). At that time it was determined that CAM did not apply to these units, since the Title V permit specified a continuous monitoring method for NOx (per 40 CFR Part 64 § 64.2(b)(1)(vi)). Since there have been no physical changes to the existing emissions units and no new units added since the first renewal, there is no change to the CAM applicability at this facility. Page 3 III. Discussion of Modifications Made Source Requested Modifications The source submitted their renewal application on August 10, 2009. In their renewal application, the source did not request any changes to their permit. Other Modifications In addition to the modifications requested by the source, the Division has included changes to make the permit more consistent with recently issued permits, include comments made by EPA on other Operating Permits, as well as correct errors or omissions identified during inspections and/or discrepancies identified during review of this renewal. The Division has made the following revisions, based on recent internal permit processing decisions and EPA comments, to the Thermo E & P Renewal Operating Permit with the source's requested modifications. These changes are as follows: Page Following Cover Page • The monitoring and compliance periods and report and certification due dates are shown as examples. The appropriate monitoring and compliance periods and report and certification due dates will be filled in after permit issuance and will be based on permit issuance date. Note that the source may request to keep the same monitoring and compliance periods and report and certification due dates as were provided in the original permit. However, it should be noted that with this option, depending on the permit issuance date, the first monitoring period and compliance period may be short (i.e. less than 6 months and less than 1 year). Section I — General Activities and Summary • Revised the language in Condition 1.1 to address attainment status of the area in which the facility is located and corrected the citation for the definition of 8-hr ozone control area. • Revised the language in Condition 1.4 to include Section IV, Condition 3.d and to note that only part of Condition 3.g is state-only enforceable (last paragraph). Note that Section IV, Condition 3.d (affirmative defense provisions for excess emissions during malfunctions) is state-only until approved by EPA in the SIP. • Condition 2 (alternative operating scenario for turbine replacement) was revised to reflect current language and to clarify that only temporary turbine replacement is allowed. Page 4 • Made minor revisions to the language in Condition 3 (prevention of significant deterioration) to be more consistent with other permits. In addition, revised this condition to address the attainment status of the area in which the facility is located. • Added a column to the Table in Condition 6.1 for the startup date of the equipment. Section 11.1 - Turbines • Based on EPA's response to a petition on another Title V operating permit, minor language changes were made to various permit conditions (both in the table and the text) to clarify that only natural gas is used as fuel for permit conditions that rely on fuel restriction for the compliance demonstration. • The performance test frequency in Condition 1.5.4 was revised to every five years. Section 11.2 — Portable Monitoring Requirements • The portable monitoring language was updated to the most recent version. Section 11.3 — Performance Test Requirements • The performance test frequency was revised to every five years. In addition, the language was revised to specify that the performance test fulfills the quarterly portable monitoring requirement for that period. "New" Section 11.5 — Emergency Compression Ignition Engines There are two engines included in the insignificant activity list that are considered insignificant under either the provisions in Colorado Regulation No. 3, Part C, Sections II.E.3.nnn (emergency generators) or xxx (stationary internal combustion engines). However, under the "catch-all" provisions in Regulation No. 3, Part C, Section II.E, sources that are subject to any federal or state applicable requirement, such as National Emission Standards for Hazardous Air Pollutants (NESHAPs), may not be considered insignificant activities. EPA promulgated National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines on March 3, 2010 which apply to these engines; therefore, they can no longer be considered insignificant activities. Although the units cannot be considered insignificant activities, since the Division has not adopted either the January 18, 2008 or March 3, 2010 revisions to the RICE MACT, both of which address area sources, the engines are still exempt from APEN reporting and minor source construction permit requirements. Engine descriptions are as follows: Page 5 Fire Pump Engine: Cummings, Model No. V-504-F2, Serial No. 3161293, rated at 187 hp, with a heat input rate of 1.7 mmBtu/hr. Emergency Generator: Detroit Diesel, Model No. V7163-7300, Serial No. 20247994, rated at 745 hp, with a heat input rate of 6.7 mmBtu/hr. The appropriate applicable requirements for these engines are as follows: • Except as provided for below, visible emissions shall not exceed 20% opacity (Reg 1, Section II.A.1) • Visible emissions shall not exceed 30% opacity, for a period or periods aggregating more than six (6) minutes in any sixty (60) minute period, during fire building, cleaning of fire boxes, soot blowing, start-up, process modifications, or adjustment or occasional cleaning of control equipment, when burning coal (Reg 1, Section II.A.4) Based on engineering judgment, the Division believes that the operational activities of fire building, cleaning of fire boxes and soot blowing do not apply to diesel engines. In addition, since these engines are not equipped with control equipment the operational activities of adjustment or occasional cleaning of control equipment also do not apply to the engines. Finally, based on engineering judgment, it is unlikely that process modifications will occur with these emergency engines. Therefore, for these units the 30% opacity provision only applies during startup. • SO2 emission shall not exceed 0.8 lbs/mmBtu (Reg 1, Section VI.B.4.b.(i)). • 40 CFR Part 63 Subpart ZZZZ requirements — management practices (oil and filter change, inspect air cleaner and inspect hoses and belts) • 40 CFR Part 63 Subpart A requirements Since these engines are not subject to any emission limitations, monitoring requirements, notification and reporting requirements the requirements in §§ 63.7. 63.8, 63.9 and 63.10 do not apply. In addition, since these emission units are existing the requirement in § 63.5 (preconstruction review and notification requirements) do not apply. Finally, Table 8 of Subpart ZZZZ indicates that operation and maintenance requirements in 63.6(e) do not apply. Therefore, the permit will only include the prohibition and circumvention requirements in § 63.4. Since these units are not subject to APEN reporting or minor source construction permit requirements, the permit will not include any requirements for calculating emissions. In their September 8, 2010 comments on the draft permit, the source requested that the requirements in 40 CFR Part 63 Subpart ZZZZ that were included in the draft permit be streamlined to clarify the substantive requirements. The Division typically includes the requirements from federal regulations as they appear in the regulation and so the Page 6 Division cannot make the requested changes. However, the Division has included a simplified list of the substantive requirements for these engines in Appendix H of the permit. Section IV— General Conditions • Added a version date to the General Conditions. • The upset requirements in the Common Provisions Regulation (general condition 3.d) were revised December 15, 2006 (effective March 7, 2007) and the revisions were included in the permit. Note that these provisions are state-only enforceable until approved by EPA into Colorado's state implementation plan (SIP). • Removed the statement in Condition 3.g (affirmative defense provisions) addressing EPA approval and state-only applicability. The EPA has approved the affirmative defense provisions, with one exception and the exception, which is state-only enforceable is identified in Section I, Condition 1.4. • Replaced the reference to "upset" in Condition 5 (emergency provisions) and 21 (prompt deviation reporting) with "malfunction". • The title for Condition 6 was changed from "Emission Standards for Asbestos" to "Emission Controls for Asbestos" and in the text the phrase "emission standards for asbestos" was changed to "asbestos control". • General Condition No. 21 (prompt deviation reporting) was revised to include the definition of prompt in 40 CFR Part 71. • Replaced the phrase "enhanced monitoring" with "compliance assurance monitoring" in General Condition No. 22.d. • Labeled the 3`d paragraph of General Condition 29.a as 29.b and added the provisions in Reg 7, Section III.C as paragraph e. Appendices • As discussed previously, the standby diesel generator and the diesel fire pump were removed from the insignificant activity list in Appendix A and are included in Section II of the permit. • Appendix B and C were replaced with revised Appendices. • Changed the mailing address for EPA in Appendix D. • Added Appendix H (simplified list of 40 CFR Pad 63 Subpart ZZZZ requirements) Page 7 N LO N O r O I— N N a N E 5 E w 0 0 = U O EoO E w 0 0 ca U pO '$:O Y ii U W c 2 O '-6 a) c al N c `.

Alternative Operating Scenarios (8/23/06 version) The following Alternative Operating Scenario (AOS) for temporary and permanent combustion turbine replacement and turbine component replacement has been reviewed in accordance with the requirements of Regulation No. 3., Part A, Section IV.A, Operational Flexibility-Alternative Operating Scenarios, and Regulation No. 3, Part B, Construction Permits, and Regulation No. 3, Part D, Major Stationary Source New Source Review and Prevention of Significant Deterioration and has been found to meet all applicable substantive and procedural requirements. This permit incorporates and shall be considered a Construction Permit for any combustion turbine replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such turbine or turbine component replacement without applying for a revision to this permit or obtaining a new Construction Permit. 2.1 Routine Turbine Component Replacements 2.1.1 The following physical or operational changes to the turbines in this permit are not considered a modification for purposes of NSPS GG,NSR/PSD, or Regulation No. 3: 2.1.1.1 Replacement of stator blades, turbine nozzles, turbine buckets, fuel nozzles, combustion chambers, seals, and shaft packings, provided that they are of the same design as the original. 2.1.1.2 Changes in the type or grade of fuel used, if the original gas turbine installation, fuel nozzles, etc. were designed for its use. 2.1.1.3 An increase in the hours of operation (unless limited by a permit condition). 2.1.1.4 Variations in operating loads within the turbine design specification. 2.1.1.5 Any physical change constituting routine maintenance, repair or replacement. 2.1.2 Turbines undergoing any of the above changes are subject to all federally applicable and state-only requirements set forth in this permit (including monitoring and record keeping), and shall be subject to any shield afforded by this permit. If replacement of any of the components listed in Conditions 2.1.1.1 or 2.1.1.5 above results in a change in serial number for the turbine, a letter explaining the action as well as a revised APEN and appropriate filing fee shall be submitted to the Division within 30 days of the replacement. 2.1.3 Note that the repair or replacement must be genuinely the same design. Except in accordance with the Alternative Operating Scenario set forth below, the Division does not consider that this allows for the entire replacement (or reconstruction) of an existing turbine with an identical new one or one similar in design or function. Rather, the Division considers the repair or replacements to encompass the repair or replacement of components at a turbine with the same (or functionally similar) components. Operating Permit Number: 95OPWE00I First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit # 95OPWE001 Page 3 2.2 Turbine Replacement The following AOS is incorporated into this permit in order to deal with a turbine breakdown or periodic routine maintenance and repair of an existing onsite turbine that requires the use of a temporary replacement turbine. "Temporary" is defined as in the same service for 270 operating days or less in any 12 month period. The 270 days is the total number of days that the turbine is in operation. If the turbine operates only part of a day, that day counts towards the 270 day total. Note that the compliance demonstrations made as part of this AOS are in addition to any compliance demonstrations required by this permit. All replacement turbines are subject to all federally applicable and state-only requirements set forth in this permit (including monitoring and record keeping), and shall be subject to any shield afforded by this permit. Results of all tests and the associated calculations pursuant required by this AOS shall be submitted to the Division within 30 calendar days of the test. Results of all tests shall be kept on site for five (5) years and made available to the Division upon request. The permittee shall maintain a log on-site to contemporaneously record the start and stop date of any turbine replacement, the manufacturer, model number, horsepower, and serial number of the turbine(s) that are replaced during the term of this permit, and the manufacturer, model number, horsepower, and serial number of the replacement turbine. 2.2.1 The permittee may temporarily replace an existing permitted turbine provided such replacement turbines are General Electric, Model No. LM5000 combustion turbines without modifying this permit, so long as the emissions from the temporary replacement turbine comply with the emission limitations for the existing permitted turbine as determined in Section 2.3. Measurement of emissions from the temporary replacement turbine shall be made as set forth in Section 2.3. The permittee may temporarily replace a grandfathered turbine or a turbine that is not subject to emission limits without modifying this permit. In this circumstance, potential annual emissions of NO„ and CO from the temporary replacement turbine must be less than or equal to the potential annual emissions of NO, and CO from the original grandfathered turbine or for the turbine that is not subject to emission limits, as determined by applying appropriate emission factors (e.g. AP-42 or manufacturer's emission factors) 2.3 Portable Analyzer Testing The permittee shall measure nitrogen oxide (NO,) and carbon monoxide (CO) emissions in the exhaust from the replacement turbine using a portable flue gas analyzer within seven (7) operating days of commencing operation of the replacement engine. Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT • Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit • Permit # 95OPWE001 Page 4 All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol (ver March 2006 or newer) as found on the Division's website at: http://www.cdphe.state.co.us/ap/down/portanalyzeproto.pdf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual or short term emission limit, the results of the tests shall be converted to a lb/hr basis and multiplied by the allowable operating hours in the month or year (whichever applies) in order to monitor compliance. If a source is not limited in its hours of operation the test results will be multiplied by the maximum number of hours in the month or year (8760), whichever applies. If the portable analyzer results indicate compliance with both the NOx and CO emission limitations, in the absence of credible evidence to the contrary, the source may certify that the turbine is in compliance with both the NOx and CO emission limitations for the relevant time period. Subject to the provisions of C.R.S. 25-7-123.1 and in the absence of credible evidence to the contrary, if the portable analyzer results fail to demonstrate compliance with either the NOx or CO emission limitations, the turbine will be considered to be out of compliance from the date of the portable analyzer test until a portable analyzer test indicates compliance with both the NOx and CO emission limitations or until the turbine is taken offline. 2.4 Additional Sources The replacement of an existing turbine with a new turbine is viewed by the Division as the installation of a new emissions unit, not "routine replacement" of an existing unit. The AOS is therefore essentially an advanced construction permit review. The AOS cannot be used for additional new emission points for any site; a turbine that is being installed as an entirely new emission point and not as part of an AOS-approved replacement of an existing onsite turbine must go through the appropriate Construction/Operating permitting process prior to installation. 3. Nonattainment Area New Source Review (NANSR) and Prevention of Significant Deterioration (PSD) 3.1 This facility is categorized as a PSD major stationary source (potential to emit of NOx > 100 tons/year). Future modifications at this facility resulting in a significant net emissions increase (see Colorado Regulation No. 3, Part D, Sections II.A.26 and 42) or a modification which is major by itself(Potential to Emit> 100 tons/year) for any pollutant listed in Colorado Regulation 3, Part D, Section II.A.42 for which the area is in attainment or attainment/maintenance may result in the application of the PSD review requirements. 3.2 This source is categorized as a NANSR major stationary source (Potential to Emit of NOx >100 tons/year). Future modifications at this facility resulting in a significant net emissions increase (see Regulation No. 3, Part D, Sections II.A.26 and 42) for VOC or NOx or a modification which is major by itself (Potential to Emit > 100 tons/year of either VOC or NOx) may result in the application of the NANSR review requirements. Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit # 95OPWE001 Page 5 3.3 There are no other Operating Permits associated with this facility for purposes of determining applicability of NANSR and PSD review regulations. 4. Accidental Release Prevention Program (112(r)) 4.1 Based on the information provided by the applicant, this facility is not subject to the provisions of the Accidental Release Prevention Program (section 112(r) of the Federal Clean Air Act). 5. Compliance Assurance Monitoring (CAM) 5.1 The following emission points at this facility use a control device to achieve compliance with an emission limitation or standard to which they are subject and have pre-control emissions that exceed or are equivalent to the major source threshold. They are therefore subject to the provisions of the CAM program as set forth in 40 CFR Part 64, as adopted by reference in Colorado Regulation No. 3, Part C, Section XIV: The turbines are not subject to CAM since at the time the CAM plan was required the Title V permit specified a continuous compliance determination method (40 CFR Part 64 § 64.2(b)(1)(vi), as adopted by reference in Colorado Regulation No. 3, Part C, Section XIV). 6.

Best Available Control Technology (BACT) shall be applied for control of Nitrogen Oxides (NOx). BACT for NOx has been determined to be steam injection with the emission limit identified in Condition 1.5.2 (Colorado Construction Permit 87WE113-1 and—2). 1.2 The combustion turbines are subject to the Reasonably Available Control Technology Requirements (RACT) for PM and CO emissions (Colorado Regulation No. 3, Part B, Section III.D.2.a). RACT has been determined as follows: 1.2.1 RACT for CO has been determined to be good combustion practices with the short- term (hourly) emission limit included in Condition 1.6. The turbines and associated control equipment shall be operated and maintained in accordance with manufacturer's requirements and good engineering practices. Such procedures and preventative maintenance schedules shall be maintained and made available to the Division upon request. 1.2.2 RACT for PM has been determined to be the use of natural gas as fuel. In the absence of credible evidence to the contrary, compliance with the PM RACT requirements is presumed provided the gas used as fuel meets the requirements in Condition 1.9. 1.3 Particulate Matter (PM and PMio) and VOC emissions are subject to the following requirements: 1.3.1 PM and VOC emissions from each turbine shall not exceed the annual limitations stated above (Colorado Construction Permits 87WE113-1 and -2 as modified under the provisions of Section I, Condition 1.3 to remove the short term (lbs/hr) limits). Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit# 95OPWE001 Page 8 Monthly emissions from each turbine shall be calculated by the end of the subsequent month using the above emission factors (from AP-42, Section 3.1, April 2000, Table 3.1-2a), the monthly natural gas consumption and the higher heating value of the gas (see Condition 1.10) in the following equation: tons/month=(EF,lbs/MMBtu)x(Natural Gas Use,MMSCF/mo)X(Heat Content of Fuel,MMBtu/MMSCF) 2000 lbs/ton Monthly emissions from each turbine shall be used in a twelve-month rolling total to monitor compliance with the annual limitations. Each month a new twelve month total shall be calculated using the previous twelve months data. 1.3.2 Particulate Matter (PM) emissions from each turbine shall not exceed 0.11 lb/MMbtu (Colorado Regulation No. 1, Section III.A.1). In the absence of credible evidence to the contrary, compliance with the particulate matter emission limits is presumed since only natural gas is permitted to be used as fuel in the turbines. The numeric PM standards were determined using the design heat input for each turbine (339 mmBtu/hr) in the following equation: PE = 0.5 x (FI)-°'2°' where: PE = particulate standard in lbs/mmBtu FI = fuel input in mmBtu/hr 1.3.3 Annual emissions of PMIo from each turbine, for the purposes of APEN reporting and payment of fess shall calculated using the above emissions factors, the annual natural gas consumption and the higher heating value of the fuel (see Condition 1.10) in the following equation: tons/year=(EF, Ibs/MMBtu)x(Natural Gas Use, MMSCF/year)X(Heat Content of Fuel,MMBtu/MMSCF) 2000 lbs/ton 1.4 Sulfur Dioxide (SO2) emissions shall not exceed the following limitations: 1.4.1 Sulfur Dioxide emissions from each turbine shall not exceed the above limitations (Colorado Construction Permits 87WE113-1 and -2). 1.4.1.1 In the absence of credible evidence to the contrary compliance with the short-term (hourly) emission limit shall be presumed provided the natural gas used as fuel meets the sulfur limit in Condition 1.9. 1.4.1.2 Compliance with annual emission limitations shall be monitored as follows: a. Monthly emissions from each turbine shall be calculated by the end of the subsequent month using the emission factor (based on permitted hourly emission limit divided by design rate of turbine (339 mmBtu/hr)), the monthly natural gas consumption and the higher heating value of the fuel (see Condition 1.10) in the equation provided Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit# 95OPWE001 Page 9 in Condition 1.3.1. Monthly emissions from each turbine shall be used in a twelve-month rolling total to monitor compliance with the annual limitations. Each month a new twelve month total shall be calculated using the previous twelve months data. b. The natural gas used as fuel shall meet the sulfur limit in Condition 1.9. 1.4.2 Sulfur Dioxide (SO2) emissions from each turbine shall not exceed 0.35 lbs/MMBtu, on a 3-hr rolling average (Colorado Regulation No. 1, Section VI.B.4.c.(ii) and VI.B.2). In the absence of credible evidence to the contrary, compliance with the SO2 limitations is presumed provided the natural gas used as fuel meets the sulfur content requirement in Condition 1.9. 1.5 Nitrogen Oxide (NOx) emissions shall not exceed the following: 1.5.1 Nitrogen Oxide Emissions from each turbine shall not exceed the above limitations (Colorado Construction Permits 87WE113-1 and -2, as modified under the provisions of Section I, Condition 1.3 to remove the hourly limitation). Compliance with the annual limitation shall be monitored using the continuous parametric monitoring system and compliance algorithm specified in Condition 1.8. Hourly emissions predicted by the algorithm from each turbine shall be summed to determine monthly emissions by the end of the subsequent month. Monthly emissions shall be used in a rolling twelve-month rolling total to monitor compliance with the annual limitation. Each month a new twelve month total shall be calculated using the previous twelve months data. 1.5.2 For BACT purposes, Nitrogen Oxide Emissions from each turbine shall not exceed 100 ppmvd at 15% O2 corrected to ISO Conditions, on a 1-hr average (Colorado Construction Permits 87WE113-1 and -2). The continuous parametric monitoring system and compliance algorithm specified in Condition 1.8 shall be used to monitor compliance with the BACT NOx emission limit. Any hours that exceed the limitation shall be reported on the excess emission report required by Condition 4.3. 1.5.3 Portable monitoring shall be conducted quarterly in accordance with the requirements in Condition 2 to monitor compliance with the NOx limits in Conditions 1.5.1 and 1.5.2. The performance testing conducted to satisfy the requirements in Condition 1.5.4 shall also satisfy the requirement to conduct portable monitoring for that quarterly period. 1.5.4 A performance test shall be conducted every five (5) years in accordance with the requirements in Condition 3 to monitor compliance with the NOx limits in Conditions 1.5.1 and 1.5.2. Note that the previous performance tests for these units were conducted on April 23, 2008. Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit# 95OPWE001 Page 10 1.6 Carbon Monoxide (CO) emissions from each turbine shall not exceed the above limitations (Colorado Construction Permits 87WE113-1 and -2). Compliance with the emission limitations shall be monitored as follows: 1.6.1 The continuous parametric monitoring system and compliance algorithm specified in Condition 1.8 shall be used to monitor compliance with the short-term (hourly) CO emission limit. Any hours that exceed the limitation shall be reported on the excess emission report required by Condition 4.3. 1.6.2 The emission factor listed above (based on permitted hourly emission limit divided by design rate of turbine (339 mmBtu/hr)) shall be used to calculate emissions. Monthly emissions shall be calculated by the end of the subsequent month using the above emission factor, the monthly natural gas consumption and the higher heating value of the gas (see Condition 1.10) in the equation provided in Condition 1.3.1. Monthly emissions from each turbine shall be used in a twelve-month rolling total to monitor compliance with the annual limitations. Each month a new twelve month total shall be calculated using the previous twelve months data. If a reference method test is conducted under the provisions of Condition 1.6.3, and the results of the testing show that either the NOx or CO emission rates/factors are greater than the emission rates/factors listed above, the permittee shall apply for a modification to this permit to reflect, at a minimum, the higher emission rates/factors within 60 days of the completion of the reference method test. 1.6.3 Portable Monitoring shall be conducted quarterly in accordance with the provisions in Condition 2 of this permit. The performance testing conducted to satisfy the requirements in Condition 1.6.4 shall also satisfy the requirement to conduct portable monitoring for that quarterly period. 1.6.4 A performance test shall be conducted in accordance with the provisions in Condition 3 of this permit. 1.7 Natural gas consumption for each turbine shall not exceed the limitations stated above (Colorado Construction Permits 87WE113-1 and -2). Natural gas use for each turbine shall be measured and recorded using the continuous parametric monitoring system specified in Condition 1.8. Monthly natural gas consumption, as determined by fuel invoices, shall be used in a twelve-month rolling total to monitor compliance with the annual limitations. Each month a new twelve month total shall be calculated using the previous twelve months data. 1.8 A continuous parametric monitoring system and compliance algorithm shall be installed and operated on each turbine to measure and record the following: 1.8.1 Low pressure turbine temperature (T-44), hourly average; Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit # 95OPWE001 Page 11 1.8.2 Ambient temperature(To), hourly average; 1.8.3 Steam injection rate, hourly average; 1.8.4 Fuel use, hourly average; 1.8.5 Compliance check for NOx and CO emissions, for each hour of operation; and 1.8.6 NOx emissions, lbs/hr The continuous parametric monitoring system and compliance algorithm shall meet the requirements in Condition 4 of this permit. 1.9 The fuel gas sulfur content shall not exceed the limitation stated above (Construction Permits 87WE113-1 and -2, as modified under the provisions of Section I, Condition 1.3 to reflect the fuel sulfur content that the SO2 emission limits are based on). The following methods may be used to demonstrate that the fuel gas sulfur requirement is met: 1.9.1 The demonstration shall be made using the gas quality characteristics in a current, valid purchase contract, tariff sheet or transportation contract for the gaseous fuel; or 1.9.2 Representative fuel sampling data provided number and frequency of sampling data meets the requirements of either sections 2.3.1.4 or 2.3.2.4 of Appendix D of 40 CFR Part 75. 1.10 The Btu content of the natural gas used to fuel these turbines shall be determined monthly from supplier supplied fuel invoices. Calculation of emissions as specified in Conditions 1.3.1, 1.4.1.2.a and 1.6.2 shall be based on the most recent fuel invoice. Calculation of annual emissions as specified in Condition 1.3.3 shall be based on the average Btu content for the year. The Btu content used in emission calculations shall be based on the lowest gross heating value of the fuel. 1.11 Regulation No. 6, Part A, Subpart A, General Provisions applies as follows: 1.11.1 No article, machine, equipment or process shall be used to conceal an emission which would otherwise constitute a violation of an applicable standard. Such concealment includes, but is not limited to, the use of gaseous diluents to achieve compliance with an opacity standard or with a standard which is based on the concentration of a pollutant in the gasses discharged to the atmosphere (40 CFR Part 60 Subpart A § 60.12). 1.11.2 At all times, including periods of startup, shutdown, and malfunction owners and operators shall to the extent practicable, maintain and operate any affected facility including associated air pollution control equipment in a manner consistent with good air pollution control practice for minimizing emissions. Determination of whether acceptable operating and maintenance procedures are being used will be based on Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit # 95OPWE001 Page 12 information available to the Division which may include, but is not limited to monitoring results, opacity observations, review of operating and maintenance procedures, and inspection of the source (Colorado Construction Permits 113-1 and -2 and 40 CFR Subpart A § 60.11(d)). 1.12 The turbines are subject to the following opacity requirements: 1.12.1 Except as provided for in Condition 1.12.2 below, no owner or operator of a source shall allow or cause the emission into the atmosphere of any air pollutant which is in excess of 20% opacity (Colorado Construction Permits 87WE113-1 and —2 and Colorado Regulation No. 1, Section II.A.1). This opacity standard applies to each turbine. 1.12.2 No owner or operator of a source shall allow or cause to be emitted into the atmosphere any air pollutant resulting from the building of a new fire, cleaning of fire boxes, soot blowing, start-up, process modifications, or adjustment or occasional cleaning of control equipment which is in excess of 30% opacity for a period or periods aggregating more than six (6) minutes in any sixty (60) consecutive minutes (Colorado Regulation No. 1, Section II.A.4). This opacity standard applies to each turbine. 1.12.3 State-Only Requirement: No owner or operator may discharge, or cause the discharge into the atmosphere of any particulate matter which is greater than 20% opacity (Colorado Regulation No. 6, Part B, Section II.C.3). This opacity standard applies to each turbine. This opacity standard applies at all times except during periods of startup, shutdown and malfunction (40 CFR Part 60 Subpart A § 60.11(c), as adopted by reference in Colorado Regulation No. 6, Part B, Section I.A). Note that this opacity requirement is more stringent than the opacity requirement in Condition 1.12.2 during periods of building of a new fire, cleaning of fire boxes, soot blowing, process modifications and adjustment or occasional cleaning of control equipment. In the absence of evidence to the contrary, compliance with the above opacity requirements shall be presumed since only natural gas is permitted to be used as fuel for these turbines. Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit# 95OPWE001 Page 13 2. Portable Monitoring Requirements (6/1/06 version) Emission measurements of nitrogen oxides (NOx) and carbon monoxide (CO) shall be conducted quarterly using a portable flue gas analyzer. At least one calendar month shall separate the quarterly tests. Note that if the engine is operated for less than 100 hrs in any quarterly period, then the portable monitoring requirements do not apply. All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol (ver March 2006 or newer) as found on the Division's website at: http://www.cdphe.state.co.us/ap/down/portanalyzeproto.pdf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual or short term emission limit, the results of the tests shall be converted to a lb/hr basis and multiplied by the allowable operating hours in the month or year (whichever applies) in order to monitor compliance. If a source is not limited in its hours of operation the test results will be multiplied by the maximum number of hours in the month or year (8760), whichever applies. If the portable analyzer results indicate compliance with both the NOx and CO emission limitations, in the absence of credible evidence to the contrary, the source may certify that the engine is in compliance with both the NOx and CO emission limitations for the relevant time period. Subject to the provisions of C.R.S. 25-7-123.1 and in the absence of credible evidence to the contrary, if the portable analyzer results fail to demonstrate compliance with either the NOx or CO emission limitations, the engine will be considered to be out of compliance from the date of the portable analyzer test until a portable analyzer test indicates compliance with both the NOx and CO emission limitations or until the engine is taken offline. For comparison with the emission rates/factors, the emission rates/factors determined by the portable analyzer tests and approved by the Division shall be converted to the same units as the emission rates/factors in the permit. If the portable analyzer tests shows that either the NOx or CO emission rates/factors are greater than the relevant ones set forth in the permit, and in the absence of subsequent testing results to the contrary (as approved by the Division), the permittee shall apply for a modification to this permit to reflect, at a minimum, the higher emission rate/factor within 60 days of the completion of the test. Results of all tests conducted shall be kept on site and made available to the Division upon request. Operating Permit Number: 95OPWE00l First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit# 95OPWE001 Page 14 3. Performance Test Requirements Performance testing shall be performed every five (5) years to monitor compliance with the NOx and CO emission limitations in Conditions 1.5.1, 1.5.2 and 1.6. Performance testing shall be conducted in accordance with the provisions of 40 CFR Part 60 Subpart GG § 60.335 for NOx and Method 10 (40 CFR Part 60 Appendix A) for CO or other test methods or procedures acceptable to the Division. Note that the previous performance tests for these units were conducted on April 23, 2008. A stack testing protocol shall be submitted for Division approval at least thirty (30) calendar days prior to any performance of the test required under this condition. No stack test required herein shall be performed without prior written approval of the protocol by the Division. The Division reserves the right to witness the test. In order to facilitate the Division's ability to make plans to witness the test, notice of the date(s) for the stack test shall be submitted to the Division at least thirty (30) calendar days prior to the test. The Division may for good cause shown, waive this thirty (30) day notice requirement. In instances when a scheduling conflict is presented, the Division shall immediately contact the permittee in order to explore the possibility of making modifications to the stack test schedule. The required number of copies of the compliance test results shall be submitted to the Division within forty- five (45) calendar days of the completion of the test unless a longer period is approved by the Division. 4. Continuous Parametric Monitoring and Compliance Algorithm Requirements 4.1 Equipment and QA/QC Requirements 4.1.1 The monitoring and recording devices specified in Conditions 1.8.1 through 1.8.4 shall be accurate to within + 5 % and approved by the Division (Colorado Construction Permits 87WE113-1 and-2). 4.1.2 The monitoring and recording devices shall be operated, maintained and calibrated in accordance with manufacturer's requirements.

(§ 63.6625(e)) 5.1.6 If you own or operate an existing emergency stationary RICE with a site rating of less than or equal to 500 brake HP located at a major source of HAP emissions or an existing emergency stationary RICE located at an area source of HAP emissions, you must install a non-resettable hour meter if one is not already installed. (§ 63.6625(f)) 5.1.7 If you operate a new or existing stationary engine, you must minimize the engine's time spent at idle during startup and minimize the engine's startup time to a period needed for appropriate and safe loading of the engine, not to exceed 30 minutes, after which time the emission standards applicable to all times other than startup in Tables la, 2a, 2c, and 2d to this subpart apply. (§ 63.6625(h)) 5.1.8 If you own or operate a stationary engine that is subject to the work, operation or management practices in Condition 5.1.2.1, you have the option of utilizing an oil analysis program in order to extend the specified oil change requirement in Condition 5.1.2.1. The oil analysis must be performed at the same frequency specified for changing the oil in Condition 5.1.2.1. The analysis program must at a minimum analyze the following three parameters: Total Base Number, viscosity, and percent water content. The condemning limits for these parameters are as follows: Total Base Number is less than 30 percent of the Total Base Number of the oil when new; viscosity of the oil has changed by more than 20 percent from the viscosity of the oil when new; or percent water content (by volume) is greater than 0.5. If all of these condemning limits are not exceeded, the engine owner or operator is not required to change the oil. If any of the limits are exceeded, the engine owner or operator must change the oil before continuing to use the engine. The owner or operator must keep records of the parameters that are analyzed as part of the program, the results of the Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit# 95OPWE00I Page 20 analysis, and the oil changes for the engine. The analysis program must be part of the maintenance plan for the engine. (§ 63.6625(i)) How do I demonstrate continuous compliance with the emission limitations and operating limitations? (§ 63.6640) 5.1.9 If you own or operate an existing emergency stationary RICE with a site rating of less than or equal to 500 brake HP located at a major source of HAP emissions, a new emergency stationary RICE with a site rating of more than 500 brake HP located at a major source of HAP emissions that was installed on or after June 12, 2006, or an existing emergency stationary RICE located at an area source of HAP emissions, you must operate the engine according to the conditions described below. (§ 63.6640(f)) 5.1.9.1 For owners and operators of emergency engines, any operation other than emergency operation, maintenance and testing, and operation in non- emergency situations for 50 hours per year, as permitted in this section, is prohibited. (§ 63.6640(f)(1)) 5.1.9.2 There is no time limit on the use of emergency stationary RICE in emergency situations. (§ 63.6640(0(2)) 5.1.9.3 You may operate your emergency stationary RICE for the purpose of maintenance checks and readiness testing, provided that the tests are recommended by Federal, State or local government, the manufacturer, the vendor, or the insurance company associated with the engine. Maintenance checks and readiness testing of such units is limited to 100 hours per year. The owner or operator may petition the Administrator for approval of additional hours to be used for maintenance checks and readiness testing, but a petition is not required if the owner or operator maintains records indicating that Federal, State, or local standards require maintenance and testing of emergency RICE beyond 100 hours per year. (§ 63.6640(f)(3)) 5.1.9.4 You may operate your emergency stationary RICE up to 50 hours per year in non-emergency situations, but those 50 hours are counted towards the 100 hours per year provided for maintenance and testing. The 50 hours per year for non-emergency situations cannot be used for peak shaving or to generate income for a facility to supply power to an electric grid or otherwise supply power as part of a financial arrangement with another entity; except that owners and operators may operate the emergency engine for a maximum of 15 hours per year as part of a demand response program if the regional transmission organization or equivalent balancing authority and transmission operator has determined there are emergency conditions that could lead to a potential electrical blackout, such as unusually low frequency, equipment overload, capacity or energy deficiency, or unacceptable voltage level. The engine may not be operated for more than 30 minutes prior to the time when the emergency condition Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit # 95OPWE001 Page 21 is expected to occur, and the engine operation must be terminated immediately after the facility is notified that the emergency condition is no longer imminent. The 15 hours per year of demand response operation are counted as part of the 50 hours of operation per year provided for non- emergency situations. The supply of emergency power to another entity or entities pursuant to financial arrangement is not limited by this Condition 5.1.9.4, as long as the power provided by the financial arrangement is limited to emergency power. (§ 63.6640(O(4)) What records must I keep? (§ 63.6655) 5.1.10 You must keep records of the maintenance conducted on the stationary RICE in order to demonstrate that you operated and maintained the stationary RICE and after- treatment control device (if any) according to your own maintenance plan if you own or operate an existing stationary CI RICE located at an area source of HAP emissions subject to management practices as shown in Conditions 5.1.2.1 through 5.1.2.3. (§ 63.6655(e) and § 63.6655(e)(3)) 5.1.11 If you own or operate an existing emergency stationary CI RICE located at an area source of HAP emissions that does not meet the standards applicable to non- emergency engines, you must keep records of the hours of operation of the engine that is recorded through the non-resettable hour meter. The owner or operator must document how many hours are spent for emergency operation, including what classified the operation as emergency and how many hours are spent for non- emergency operation. If the engines are used for demand response operation, the owner or operator must keep records of the notification of the emergency situation, and the time the engine was operated as part of demand response. (§ 63.6655(f) and § 63.6655(O(2)) 5.2 Sulfur Dioxide (SO2) emissions shall not exceed 0.8 lbs/mmBtu (Colorado Regulation No. 1, Section VI.B.4.b.(i)). In the absence of credible evidence to the contrary, compliance with the SO2 emission limitation shall be presumed since only diesel fuel is permitted to be used as fuel in these engines. 5.3 Opacity of emissions from the engine shall not exceed the following: 5.3.1 Except as provided for in Condition 5.3.2 below, no owner or operator of a source shall allow or cause the emission into the atmosphere of any air pollutant which is in excess of 20% opacity (Colorado Regulation No. 1, Section II.A.1). 5.3.2 No owner or operator of a source shall allow or cause to be emitted into the atmosphere any air pollutant resulting from startup which is in excess of 30% opacity for a period or periods aggregating more than six (6) minutes in any sixty (60) consecutive minutes (Colorado Regulation No. 1, Section II.A.4). Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit# 95OPWE001 Page 22 Compliance with these limitations shall be monitored by conducting opacity observations in accordance with EPA Reference Method 9 as follows: 5.3.3 An engine startup period of less than 60 minutes shall not require a startup opacity observation. If the engine startup period is greater than 60 minutes, one opacity observation shall be made for each consecutive 4 hour period of startup during daylight hours. In addition, a record shall be kept of the date and time the engine started and when it was shutdown. 5.3.4 Continued operation of the engine after the completion of the startup period shall require monthly opacity observations. If the startup and operation of the engine lasts less than a total of 4 hours from engine start to engine stop, in any one day no opacity observations are required for that day. 5.3.5 If no opacity observations are made pursuant to Conditions 5.3.3 and 5.3.4 above, then an opacity observation shall be conducted annually. 5.3.6 All opacity observations shall be performed by an observer with current and valid Method 9 certification. Results of Method 9 readings and a copy of the certified Method 9 reader's certificate shall be kept on site and made available to the Division upon request. 5.4 These engines are subject to the requirements in 40 CFR part 63 Subpart A "General Provisions", as adopted by reference in Colorado Regulation No. 8, Part E, Section I as specified in 40 CFR Part 63 Subpart ZZZZ § 63.6665.

Affirmative Defense Provision for Excess Emissions during Malfunctions Note that until such time as the U.S. EPA approves this provision into the Colorado State Implementation Plan (SIP), it shall be enforceable only by the State. An affirmative defense to a claim of violation under these regulations is provided to owners and operators for civil penalty actions for excess emissions during periods of malfunction. To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement, the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of evidence that: (i) The excess emissions were caused by a sudden,unavoidable breakdown of equipment, or a sudden, unavoidable failure of a process to operate in the normal or usual manner,beyond the reasonable control of the owner or operator; (ii) The excess emissions did not stem from any activity or event that could have reasonably been foreseen and avoided,or planned for, and could not have been avoided by better operation and maintenance practices; (iii) Repairs were made as expeditiously as possible when the applicable emission limitations were being exceeded; (iv) The amount and duration of the excess emissions(including any bypass)were minimized to the maximum extent practicable during periods of such emissions; (v) All reasonably possible steps were taken to minimize the impact of the excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation(if at all possible); (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed, contemporaneous operating logs or other relevant evidence; (viii) The excess emissions were not part of a recurring pattern indicative of inadequate design, operation, or maintenance; (ix) At all times,the facility was operated in a manner consistent with good practices for minimizing emissions. This section is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator, and shall not constitute an additional applicable requirement; and (x) During the period of excess emissions, there were no exceedances of the relevant ambient air quality standards established in the Commissions' Regulations that could be attributed to the emitting source. The owner or operator of the facility experiencing excess emissions during a malfunction shall notify the division verbally as soon as possible, but no later than noon of the Division's next working day, and shall submit written notification following the initial occurrence of the excess emissions by the end of the source's next reporting period. The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief The Affirmative Defense Provision does not apply to failures to meet federally promulgated performance standards or emission limits, including, but not limited to, new source performance standards and national emission standards for hazardous air pollutants. The affirmative defense provision does not apply to state implementation plan (sip) limits or permit limits that have been set taking into account potential emissions during malfunctions, including, but not necessarily limited to, certain limits with 30-day or longer averaging times, limits that indicate they apply during malfunctions, and limits that indicate they apply at all times or without exception.

Circumvention Clause A person shall not build,erect, install, or use any article, machine, equipment, condition, or any contrivance, the use of which, without resulting in a reduction in the total release of air pollutants to the atmosphere, reduces or conceals an emission which would otherwise constitute a violation of this regulation. No person shall circumvent this regulation by using more openings than is considered normal practice by the industry or activity in question. f. Compliance Certifications For the purpose of submitting compliance certifications or establishing whether or not a person has violated or is in violation of any standard in the Colorado State Implementation Plan, nothing in the Colorado State Implementation Plan shall preclude the use, including the exclusive use,of any credible evidence or information,relevant to whether a source would have been in compliance with applicable requirements if the appropriate performance or compliance test or procedure had been performed. Evidence that has the effect of making any relevant standard or permit term more stringent shall not be credible for proving a violation of the standard or permit term. When compliance or non-compliance is demonstrated by a test or procedure provided by permit or other applicable requirement,the owner or operator shall be presumed to be in compliance or non-compliance unless other relevant credible evidence overcomes that presumption. g. Affirmative Defense Provision for Excess Emissions During Startup and Shutdown An affirmative defense is provided to owners and operators for civil penalty actions for excess emissions during periods of startup and shutdown. To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement, the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of the evidence that: (i) The periods of excess emissions that occurred during startup and shutdown were short and infrequent and could not have been prevented through careful planning and design; (ii) The excess emissions were not part of a recurring pattern indicative of inadequate design, operation or maintenance; (iii) If the excess emissions were caused by a bypass (an intentional diversion of control equipment),then the bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; (iv) The frequency and duration of operation in startup and shutdown periods were minimized to the maximum extent practicable; (v) All possible steps were taken to minimize the impact of excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation(if at all possible); (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed, contemporaneous operating logs or other relevant evidence;and, (viii) At all times,the facility was operated in a manner consistent with good practices for minimizing emissions. This subparagraph is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator, and shall not constitute an additional applicable requirement. The owner or operator of the facility experiencing excess emissions during startup and shutdown shall notify the Division verbally as soon as possible, but no later than two(2)hours after the start of the next working day, and shall submit written quarterly notification following the initial occurrence of the excess emissions. The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief. Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit # 95OPWE001 Page 29 The Affirmative Defense Provision does not apply to State Implementation Plan provisions or other requirements that derive from new source performance standards or national emissions standards for hazardous air pollutants, or any other federally enforceable performance standard or emission limit with an averaging time greater than twenty- four hours. In addition, an affirmative defense cannot be used by a single source or small group of sources where the excess emissions have the potential to cause an exceedance of the ambient air quality standards or Prevention of Significant Deterioration(PSD) increments. In making any determination whether a source established an affirmative defense,the Division shall consider the information within the notification required above and any other information the Division deems necessary, which may include,but is not limited to,physical inspection of the facility and review of documentation pertaining to the maintenance and operation of process and air pollution control equipment. 4. Compliance Requirements Regulation No. 3, 5 CCR 1001-5,Part C, §§ III.C.9., V.C.I I. & 16.d. and §25-7-122.1(2),C.R.S. a. The permittee must comply with all conditions of the Operating Permit.

The permittee must comply with all conditions of this operating permit. Any permit noncompliance constitutes - a violation of the Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or for denial of a permit renewal application. The Part 70 Operating Permit program requires three types of reports to be filed for all permits. All required reports must be certified by a responsible official. Report#1: Monitoring Deviation Report (due at least every six months) For purposes of this operating permit, the Division is requiring that the monitoring reports are due every six months unless otherwise noted in the permit. All instances of deviations from permit monitoring requirements must be clearly identified in such reports. For purposes of this operating permit, monitoring means any condition determined by observation, by data from any monitoring protocol, or by any other monitoring which is required by the permit as well as the recordkeeping associated with that monitoring. This would include, for example, fuel use or process rate monitoring, fuel analyses, and operational or control device parameter monitoring. Report#2: Permit Deviation Report (must be reported "promptly") In addition to the monitoring requirements set forth in the permits as discussed above, each and every requirement of the permit is subject to deviation reporting. The reports must address deviations from permit requirements, including those attributable to malfunctions as defined in this Appendix, the probable cause of Operating Permit Number: 95OPWE00I First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 2 such deviations, and any corrective actions or preventive measures taken. All deviations from any term or condition of the permit are required to be summarized or referenced in the annual compliance certification. For purposes of this operating permit, "malfunction" shall refer to both emergency conditions and malfunctions. Additional discussion on these conditions is provided later in this Appendix. For purposes of this operating permit, the Division is requiring that the permit deviation reports are due as set forth in General Condition 21. Where the underlying applicable requirement contains a definition of prompt or otherwise specifies a time frame for reporting deviations, that definition or time frame shall govern. For example, quarterly Excess Emission Reports required by an NSPS or Regulation No. 1, Section IV. In addition to the monitoring deviations discussed above, included in the meaning of deviation for the purposes of this operating permit are any of the following: (1) A situation where emissions exceed an emission limitation or standard contained in the permit; (2) A situation where process or control device parameter values demonstrate that an emission limitation or standard contained in the permit has not been met; (3) A situation in which observations or data collected demonstrates noncompliance with an emission limitation or standard or any work practice or operating condition required by the permit; or, (4) A situation in which an excursion or exceedance as defined in 40CFR Part 64 (the Compliance Assurance Monitoring (CAM) Rule) has occurred. (only if the emission point is subject to CAM) For reporting purposes, the Division has combined the Monitoring Deviation Report with the Permit Deviation Report. All deviations shall be reported using the following codes: 1 = Standard: When the requirement is an emission limit or standard 2 = Process: When the requirement is a production/process limit 3= Monitor: When the requirement is monitoring 4 =Test: When the requirement is testing 5 =Maintenance: When required maintenance is not performed 6 = Record: When the requirement is recordkeeping 7 = Report: When the requirement is reporting 8= CAM: A situation in which an excursion or exceedance as defined in 40CFR Part 64 (the Compliance Assurance Monitoring (CAM) Rule) has occurred. 9=Other: When the deviation is not covered by any of the above categories Report#3: Compliance Certification (annually, as defined in the permit) Submission of compliance certifications with terms and conditions in the permit, including emission limitations, standards, or work practices, is required not less than annually. Compliance Certifications are intended to state the compliance status of each requirement of the permit over the certification period. They must be based, at a minimum, on the testing and monitoring methods specified in the Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 3 permit that were conducted during the relevant time period. In addition, if the owner or operator knows of other material information (i.e. information beyond required monitoring that has been specifically assessed in relation to how the information potentially affects compliance status), that information must be identified and addressed in the compliance certification. The compliance certification must include the following: • The identification of each term or condition of the permit that is the basis of the certification; • Whether or not the method(s) used by the owner or operator for determining the compliance status with each permit term and condition during the certification period was the method(s) specified in the permit. Such methods and other means shall include, at a minimum, the methods and means required in the permit. If necessary, the owner or operator also shall identify any other material information that must be included in the certification to comply with section 113(c)(2) of the Federal Clean Air Act, which prohibits knowingly making a false certification or omitting material information; • The status of compliance with the terms and conditions of the permit, and whether compliance was continuous or intermittent. The certification shall identify each deviation and take it into account in the compliance certification. Note that not all deviations are considered violations.' • Such other facts as the Division may require, consistent with the applicable requirements to which the source is subject, to determine the compliance status of the source. The Certification shall also identify as possible exceptions to compliance any periods during which compliance is required and in which an excursion or exceedance as defined under 40 CFR Part 64 (the Compliance Assurance Monitoring (CAM) Rule) has occurred. (only for emission points subject to CAM) Note the requirement that the certification shall identify each deviation and take it into account in the compliance certification. Previously submitted deviation reports, including the deviation report submitted at the time of the annual certification, may be referenced in the compliance certification. Startup, Shutdown, Malfunctions and Emergencies Understanding the application of Startup, Shutdown, Malfunctions and Emergency Provisions, is very important in both the deviation reports and the annual compliance certifications. Startup, Shutdown, and Malfunctions Please note that exceedances of some New Source Performance Standards (NSPS) and Maximum Achievable Control Technology (MACT) standards that occur during Startup, Shutdown or Malfunctions may not be considered to be non-compliance since emission limits or standards often do not apply unless specifically stated in the NSPS. Such exceedances must, however, be reported as excess emissions per the NSPS/MACT rules and would still be noted in the deviation report. In regard to compliance certifications, the permittee should be ' For example, given the various emissions limitations and monitoring requirements to which a source may be subject, a deviation from one requirement may not be a deviation under another requirement which recognizes an exception and/or special circumstances relating to that same event. Operating Permit Number: 95OPWE001 First Issued: 1/1/99 Renewed: DRAFT • Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 4 confident of the information related to those deviations when making compliance determinations since they are subject to Division review. The concepts of Startup, Shutdown and Malfunctions also exist for Best Available Control Technology (BACT) sources, but are not applied in the same fashion as for NSPS and MACT sources. Emergency Provisions Under the Emergency provisions of Part 70 certain operational conditions may act as an affirmative defense against enforcement action if they are properly reported. DEFINITIONS Malfunction (NSPS) means any sudden, infrequent, and not reasonably preventable failure of air pollution control equipment, process equipment, or a process to operate in a normal or usual manner. Failures that are caused in part by poor maintenance or careless operation are not malfunctions. Malfunction (SIP) means any sudden and unavoidable failure of air pollution control equipment or process equipment or unintended failure of a process to operate in a normal or usual manner. Failures that are primarily caused by poor maintenance, careless operation, or any other preventable upset condition or preventable equipment breakdown shall not be considered malfunctions. Emergency means any situation arising from sudden and reasonably unforeseeable events beyond the control of the source, including acts of God, which situation requires immediate corrective action to restore normal operation, and that causes the source to exceed a technology-based emission limitation under the permit, due to unavoidable increases in emissions attributable to the emergency. An emergency shall not include noncompliance to the extent caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error.

If it was not,mark "no" and attach additional information/explanation. Note whether the compliance status with of each term and condition provided was continuous or intermittent. "Intermittent Compliance" can mean either that noncompliance has occurred or that the owner or operator has data sufficient to certify compliance only on an intermittent basis. Certification of intermittent compliance therefore does not necessarily mean that any noncompliance has occurred. NOTE: The Periodic Monitoring requirements of the Operating Permit program rule are intended to provide assurance that even in the absence of a continuous system of monitoring the Title V source can demonstrate whether it has operated in continuous compliance for the duration of the reporting period. Therefore, if a source 1) conducts all of the monitoring and recordkeeping required in its permit, even if such activities are done periodically and not continuously, and if 2) such monitoring and recordkeeping does not indicate non-compliance, and if 3) the Responsible Official is not aware of any credible evidence that indicates non-compliance, then the Responsible Official can certify that the emission point(s) in question were in continuous compliance during the applicable time period.

Page 1 APPENDIX H Simplified Version of the Substantive Requirements in Section II, Condition 5.1 The following list is intended to provide a simplified version of the substantive requirements in Section II, Condition 5.1. Section II, Condition 5.1 of the permit includes the requirements applicable to existing emergency compression ignition engines located at area sources in 40 CFR Part 63 Subpart ZZZZ. It should be noted that compliance or non-compliance with the applicable requirements in 40 CFR Part 63 Subpart ZZZZ shall be based on the language in the regulation, which has been included in Section II, Condition 5.1. The following requirements take effect on May 3, 2013. Work Practice Requirements: (Section II, Condition 5.1.2 (§ 66.6603(a), Table 2d of Subpart ZZZZ)) • Change oil and filter every 500 hours of operation or annually whichever comes first. • Inspect air cleaner every 1,000 hours of operation or annually whichever comes first. • Inspect all hoses and belts every 500 hours of operation or annually whichever comes first, and replace as necessary. Note that in lieu of performing oil changes, an oil analysis program may be used— see Section II, Condition 5.1.8 (§ 63.6625). Also note that if the engine is operating during an emergency and it is not possible to shut it down to perform the required maintenance, is shall be performed as soon as practicable after the emergency has ended (see Section II, Condition 5.1.2.5 (Subpart ZZZZ Table 2d footnote)) Operating and Monitoring Requirements • Each engine shall be operated and maintained in accordance with manufacturer's instructions or source developed maintenance plan. (Section II, Condition 5.1.5 (§ 63.6625(e)) • Each engine shall be equipped with a non-resettable hour meter. (Section II, Condition 5.1.6 (§ 63.6625(f)) • Idling during startup shall not exceed 30 minutes. (Section II, Condition 5.1.7 (§ 63.6625(e)) Operating Restrictions • There is no time limit on operation of the engine during an emergency. (Section II, Condition 5.1.9.2 (§ 63.6640(f)(2)) • Operation of the engine during maintenance checks and readiness testing is limited to 100 hours per year. (Section II, Condition 5.1.9.2 (§ 63.6640(f)(3)) Operating Permit Number: 95OP W E001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix H Simplified Version of the Substantive Requirements in Section II, Condition 5.1. Page 2 • Operation of the engine during non-emergency periods is limited to 50 hours per year. The 50 hours per year is counted towards the 100 hours per year allowed for maintenance checks and readiness testing. The 50 hours for non-emergency operation is subject to the following limitations: o Cannot be used for peak shaving or to generate income o The engine can be operated for 15 hours per year as part of a demand response program if the appropriate authorities have determined that there are emergency conditions that could lead to a potential blackout. The 15 hours per year is counted towards the 50 hours per year of non- emergency operation. (Section II, Condition 5.1.9.4 (§ 63.6640(0(4)) Recordkeeping Requirements • Retain maintenance records (Section II, Condition 5.1.10 (§ 63.6655(e) and (e)(3)) • Retain records of the hours of operation, as follows: o How many hours spent on emergency operation, including what classified the operation as an emergency o How many hours spent on non-emergency operation o If used for demand response, keep records of the notification of emergency situation and the time the engine operated for demand response.

For the most part, the comments primarily consist of a red-lined version of the draft permit. In general,the Division has incorporated Thermo's comments as requested, with the following exceptions: Item 1: Alternative Operating Scenario—Portable Analyzer Testing, Section I, Condition 2.3. Thermo requested that the portable monitoring language be revised to specify that a subsequent portable monitoring test was required within 14 days of the initial portable monitoring test that indicated an exceedance of either the NOx or CO emission limitations. Response: As a result of public comments received on another Title V permit and subsequent discussions with EPA, the Division developed a protocol for portable monitoring so that the results of the portable monitoring could be considered directly enforceable. Following this action, the Division revised our portable monitoring language and the portable monitoring language contained in the alternative operating scenarios for both turbine and engine replacement and has been including the revised language in permits as they are revised. Since the Division considers that portable monitoring results conducted in accordance with the Division's protocol are directly enforceable, the requested change cannot be made. Item 2: Section II, Condition 5.1. Thermo requested that the provisions in Section II, Condition 5.1 be streamlined. Response: For the most part, the language included in Section II, Condition 5.1 is directly from 40 CFR Part 63 Subpart ZZZZ and the Division cannot revise the language in these conditions. However, the Division has included a simplified list of the substantive requirements in Appendix H of the permit. Please be aware that the information in Appendix H is intended to provide a simplified list of the requirements and that compliance and/or non-compliance with the requirements of 40 CFR Part 63 Subpart ZZZZ shall be based on the language in the regulation which has been included in Section II, Condition 5.1 of the permit. Mr. Richard Recor, Thermo Power and Electric, LLC September 22, 2010 Response to Comments on Draft Permit Page 2 The next step for this draft renewal permit will be to put it out for a 30-day Public Comment period. After that, the proposed permit will go to EPA Region VIII for a 45-day review period. The regulations also require that the applicant receive written notice of their right to a formal hearing before the Air Quality Control Commission at the same time that the Public Comment packet goes out. You will receive a separate letter containing that information. We appreciate that you took the time to thoroughly review this draft.

I wanted to verify that I am listing the engines correctly. Is the Cummins (187 hp), the emergency generator or is it the Detroit Diesel (745 hp)? From my e-mail, it appeared that the Cummins was the generator but I would have thought the emergency generator was the larger engine and the water pump the smaller engine. >>> "Kevin Lewis" <klewis@airsci.com> 9/15/2010 4:10 PM >>> Still working on it.

No methylene chloride paint stripping chemicals are used. Also, included is a redline/strikeout of the permit with our comments. Most of the comments are editorial. Two main comments are as follows: 1. The new RICE conditions 2. Portable analyzer testing and compliance The new RICE conditions The renewal permit contains the applicable RICE sections verbatim from 40 CFR 63. Although this makes sense from a legal perspective, it may be a little difficult to follow by the operators. If possible, we would like these conditions streamlined -see redline/strikeout for example changes. Portable analyzer testing and compliance Section I, Condition 2.3 -The current permit requires a 14-day follow-up portable analyzer test if the initial portable analyzer test fails. If the follow-up test also fails, then a reference method test is conducted within 45 days, which is used to determine the final compliance status. The proposed renewal permit establishes compliance based on the initial portable analyzer test only. This change to the permit does not allow the facility any time to react to a failed portable analyzer test, or even to determine if the portable analyzer test is valid. Therefore, we would prefer that the original conditions be left intact. However, to the extent that these conditions have to be changed, we request that the new conditions at least require a follow-up portable analyzer test within 14 days to verify compliance or non-compliance. See proposed redline/strikeout in the attached file. The proposed redline/strikeout requires a second portable analyzer within 14 days if the initial test fails. These 14 days will allow the facility to determine if the initial failed test is due to either an invalid test or a real emissions problem. If it is the latter, the 14 days would allow the facility time to take corrective action, and hopefully fix the problem. This can only be accomplished if the turbine is allowed to run (for a limited time) to troubled shoot and fix the problem.

Electricity for sale is produced by two(2)combustion turbines and a steam turbine. Each combustion turbine serves a generator rated at 42.5 MW (name-plate) and the steam turbine generator is rated at 16.3 MW (name-plate). In addition to the combustion turbines, significant emission units at this facility consist of one (1) diesel-fired engine driving an emergency generator and one(I)diesel-fired engine driving a fire pump. This facility is located in an area classified as attainment/maintenance for carbon monoxide (CO). Under that classification, all SIP-approved requirements for CO will continue to apply in order to prevent backsliding under the provisions of Section 1100)of the Federal Clean Air Act. This Area is classified as non-attainment for ozone and is part of the 8-hr Ozone Control Area as defined in Regulation No.7,Section II.A.1. Wyoming, an affected state is within 50 miles of the plant. Rocky Mountain National Park, a Federal Class I designated area is within 100 kilometers of the plant. 1.2 Until such time as this permit expires or is modified or revoked, the permittee is allowed to discharge air pollutants from this facility in accordance with the requirements, limitations, and conditions of this permit. 1.3 This Operating Permit incorporates the applicable requirements contained in the underlying construction permits, and does not affect those applicable requirements, except as modified during review of the application or as modified subsequent to permit issuance using the modification procedures found in Regulation No. 3, Part C. These Part C procedures meet all applicable substantive New Source Review requirements of Part B. Any revisions made using the provisions of Regulation No. 3, Part C shall become new applicable requirements for purposes of this operating permit and shall survive reissuance. This permit incorporates the applicable requirements (except as noted in Section II) from the following construction permits: 87WE113-I and 87WE113-2. 1.4 All conditions in this permit are enforceable by US Environmental Protection Agency, Colorado Air Pollution Control Division (hereinafter Division) and its agents, and citizens unless otherwise specified. State-only enforceable conditions are: Permit Condition Number(s): Section II, Condition 1.12.3 (opacity) and Section IV - Conditions 3.d, 3.g (last paragraph), 14 and 18(as noted) 1.5 All information gathered pursuant to the requirements of this permit is subject to the Recordkeeping and Reporting requirements listed under Condition 22 of the General Conditions in Section IV of this permit. Either electronic or hard copy records are acceptable. Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE00I Page 2 2. Alternative Operating Scenarios(8/23/06 version) The following Alternative Operating Scenario (AOS) for temporary and permanent combustion turbine replacement and turbine component replacement has been reviewed in accordance with the requirements of Regulation No.3.,Part A, Section IV.A,Operational Flexibility-Alternative Operating Scenarios,and Regulation No.3, Part B,Construction Permits,and Regulation No. 3,Part D, Major Stationary Source New Source Review and Prevention of Significant Deterioration and has been found to meet all applicable substantive and procedural requirements. This permit incorporates and shall be considered a Construction Permit for any combustion turbine replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such turbine or turbine component replacement without applying for a revision to this permit or obtaining a new Construction Permit. 2.1 Routine Turbine Component Replacements 2.1.1 The following physical or operational changes to the turbines in this permit are not considered a modification for purposes ofNSPS GG,NSR/PSD,or Regulation No.3: 2.1.1.1 Replacement of stator blades, turbine nozzles, turbine buckets, fuel nozzles, combustion chambers, seals, and shaft packings, provided that they are of the same design as the original. 2.1.1.2 Changes in the type or grade of fuel used, if the original gas turbine installation,fuel nozzles.etc.were designed for its use. 2.1.1.3 An increase in the hours of operation (unless limited by a permit condition). 2.1.1.4 Variations in operating loads within the turbine design specification. 2.1.1.5 Any physical change constituting routine maintenance,repair or replacement. 2.1.2 Turbines undergoing any of the above changes are subject to all federally applicable and state-only requirements set forth in this permit(including monitoring and record keeping),and shall be subject to any shield afforded by this permit. If replacement of any of the components listed in Conditions 2.1.1.1 or 2.1.1.5 above results in a change in serial number for the turbine, a letter explaining the action as well as a revised APEN and appropriate filing fee shall be submitted to the Division within 30 days of the replacement. 2.1.3 Note that the repair or replacement must be genuinely the same design. Except in accordance with the Alternative Operating Scenario set forth below,the Division does not consider that this allows for the entire replacement (or reconstruction) of an existing turbine with an identical new one or one similar in design or function. Rather, the Division considers the repair or replacements to encompass the repair or replacement of components at a turbine with the same (or functionally similar) components. Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit it 95OPWE001 Page 3 2.2 Turbine Replacement The following AOS is incorporated into this permit in order to deal with a turbine breakdown or periodic routine maintenance and repair of an existing onsite turbine that requires the use of a temporary replacement turbine. "Temporary"is defined as in the same service for operating --{Deleted:90 days or less in any 12 month period. The 270 days is the total number of days that the turbine is in operation. If the turbine operates only part of a day,that day counts towards the Iday total. ..--{Deleted:90 Note that the compliance demonstrations made as part of this AOS are in addition to any compliance demonstrations required by this permit. All replacement turbines are subject to all federally applicable and state-only requirements set forth in this permit(including monitoring and record keeping),and shall be subject to any shield afforded by this permit. Results of all tests and the associated calculations pursuant required by this AOS shall be submitted to the Division within 30 calendar days of the test. Results of all tests shall be kept on site for five(5)years and made available to the Division upon request. The permittee shall maintain a log on-site to contemporaneously record the start and stop date of any turbine replacement,the manufacturer,model number,horsepower, and serial number of the turbine(s)that are replaced during the term of this permit,and the manufacturer, model number, horsepower,and serial number of the replacement turbine. 2.2.1 The permittee may temporarily replace an existing permitted turbine provided such replacement turbines are General Electric, Model No. LM5000 combustion turbines without modifying this permit, so long as the emissions from the temporary replacement turbine comply with the emission limitations for the existing permitted turbine as determined in Section 2.3. Measurement of emissions from the temporary replacement turbine shall be made as set forth in Section 2.3. The permittee may temporarily replace a grandfathered turbine or a turbine that is not subject to emission limits without modifying this permit. In this circumstance, potential annual emissions of NO, and CO from the temporary replacement turbine must be less than or equal to the potential annual emissions of NO,and CO from the original grandfathered turbine or for the turbine that is not subject to emission limits, as determined by applying appropriate emission factors(e.g.AP-42 or manufacturer's emission factors) 2.3 Portable Analyzer Testing The permittee shall measure nitrogen oxide(NO,) and carbon monoxide (CO) emissions in the exhaust from the replacement turbine using a portable flue gas analyzer within seven (7) pperating days of commencing operation of the replacement engine. -{Deleted:calendar Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 4 All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol (ver March 2006 or newer) as found on the Division's website at:http://www.cdphe.state.co.us/ap/down/portanalyzeproto.pdf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual or short term emission limit, the results of the tests shall be converted to a lb/hr basis and multiplied by the allowable operating hours in the month or year (whichever applies) in order to monitor compliance. If a source is not limited in its hours of operation the test results will be multiplied by the maximum number of hours in the month or year(8760),whichever applies. If the portable analyzer results indicate compliance with both the NOx and CO emission limitations, in the absence of credible evidence to the contrary, the source may certify that the turbine is in compliance with both the NOx and CO emission limitations for the relevant time period. An exceedance of either the NOx or CO emission limitation during the initial portable flue gas —{Formatted:Subscript analyzer test shall require a subsequent portable analyzer test within 14 operating days of the initial test. Subject to the provisions of C.R.S. 25-7-123.1 and in the absence of credible evidence to the contrary, if the subsequent portable analyzer results fail to demonstrate compliance with either the NOx or CO emission limitations,the turbine will be considered to be out of compliance from the date of the portable analyzer test until a portable analyzer test indicates compliance with both the NOx and CO emission limitations or until the turbine is taken offl ine. 2.4 Additional Sources The replacement of an existing turbine with a new turbine is viewed by the Division as the installation of a new emissions unit, not"routine replacement"of an existing unit. The AOS is therefore essentially an advanced construction permit review. The AOS cannot be used for additional new emission points for any site; a turbine that is being installed as an entirely new emission point and not as part of an AOS-approved replacement of an existing onsite turbine must go through the appropriate Construction/Operating permitting process prior to installation. 3. Nonattainment Area New Source Review (NANSR) and Prevention of Significant Deterioration (PSD) 3.1 This facility is categorized as a PSD major stationary source (potential to emit of NOx > 100 tons/year). Future modifications at this facility resulting in a significant net emissions increase (see Colorado Regulation No. 3, Part D. Sections II,A.26 and 42) or a modification which is .--{Deleted:n major by itself(Potential to Emit> 100 tons/year)for any pollutant listed in Colorado Regulation 3, Part D, Section II.A.42 for which the area is in attainment or attainment/maintenance may result in the application of the PSD review requirements. 3.2 This source is categorized as a NANSR major stationary source(Potential to Emit of NOx>100 tons/year). Future modifications at this facility resulting in a significant net emissions increase Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 5 (see Regulation No. 3,Part D,Sections II.A.26 and 42)for VOC or NOx or a modification which is major by itself(Potential to Emit > 100 tons/year of either VOC or NOx) may result in the application of the NANSR review requirements. 3.3 There are no other Operating Permits associated with this facility for purposes of determining applicability of NANSR and PSD review regulations. 4. Accidental Release Prevention Program(112(r)) 4.1 Based on the information provided by the applicant,this facility is not subject to the provisions of the Accidental Release Prevention Program(section 112(r)of the Federal Clean Air Act). 5. Compliance Assurance Monitoring(CAM) 5.1 The following emission points at this facility use a control device to achieve compliance with an emission limitation or standard to which they are subject and have pre-control emissions that exceed or are equivalent to the major source threshold. They are therefore subject to the provisions of the CAM program as set forth in 40 CFR Part 64, as adopted by reference in Colorado Regulation No.3,Part C,Section XIV: The turbines are not subject to CAM since at the time the CAM plan was required the Title V permit specified a continuous compliance determination method (40 CFR Part 64 § 64.2(6)(1)(vi),as adopted by reference in Colorado Regulation No.3,Part C,Section XIV). 6.

Best Available Control Technology(BACT) shall be applied for control of Nitrogen Oxides(NOx). BACT for NOx has been determined to be steam injection with the emission limit identified in Condition 1.5.2(Colorado Construction Permit 87WE113-1 and—2). 1.2 The combustion turbines are subject to the Reasonably Available Control Technology Requirements(RACT)for PM and CO emissions(Colorado Regulation No.3,Part B,Section III.D.2.a). RACT has been determined as follows: 1.2.1 RACT for CO has been determined to be good combustion practices with the short- term(hourly) emission limit included in Condition 1.6. The turbines and associated control equipment shall be operated and maintained in accordance with manufacturer's requirements and good engineering practices. Such procedures and preventative maintenance schedules shall be maintained and made available to the Division upon request. 1.2.2 RACT for PM has been determined to be the use of natural gas as fuel. In the absence of credible evidence to the contrary, compliance with the PM RACT requirements is presumed provided the gas used as fuel meets the requirements in Condition 1.9. 1.3 Particulate Matter(PM and PMi0)and VOC emissions are subject to the following requirements: 1.3.1 PM and VOC emissions from each turbine shall not exceed the annual limitations stated above(Colorado Construction Permits 87WEI13-I and -2 as modified under the provisions of Section I, Condition 1.3 to remove the short term (lbs/hr) limits). Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 8 Monthly emissions from each turbine shall be calculated by the end of the subsequent month using the above emission factors (from AP-42, Section 3.1, April 2000,Table 3.1-2a),the monthly natural gas consumption and the higher heating value of the gas (see Condition 1.10)in the following equation: tons/month=(EF,lbs/MMBtu)x(Natural Gas Use,MMSCF/mo)X(Heat Content of Fuel,MMBtu/MMSCFI 2000 lbs/ton Monthly emissions from each turbine shall be used in a twelve-month rolling total to monitor compliance with the annual limitations. Each month a new twelve month total shall be calculated using the previous twelve months data. 1.3.2 Particulate Matter (PM) emissions from each turbine shall not exceed 0.11 Ib/MMbtu (Colorado Regulation No. I, Section III.A.1). In the absence of credible evidence to the contrary, compliance with the particulate matter emission limits is presumed since only natural gas is permitted to be used as fuel in the turbines. The numeric PM standards were determined using the design heat input for each turbine(339 mmBtu/hr)in the following equation: PE=0.5 x(FI)-°20` where: PE=particulate standard in lbs/mmBtu FI=fuel input in mmBtu/hr 1.3.3 Annual emissions of PM10 from each turbine,for the purposes of APEN reporting and payment of fess shall calculated using the above emissions factors,the annual natural gas consumption and the higher heating value of the fuel (see Condition 1.10) in the following equation: tons/year=(EF lbs/MMBtu)x(Natural Gas Use MMSCF/year)X(Heat Content of Fuel MMBra/MMSCF1 2000 lbs/ton 1.4 Sulfur Dioxide(SO2)emissions shall not exceed the following limitations: 1.4.1 Sulfur Dioxide emissions from each turbine shall not exceed the above limitations (Colorado Construction Permits 87WE113-1 and-2). 1.4.1.1 In the absence of credible evidence to the contrary compliance with the short-term (hourly) emission limit shall be presumed provided the natural gas used as fuel meets the sulfur limit in Condition 1.9. 1.4.1.2 Compliance with annual emission limitations shall be monitored as follows: a. Monthly emissions from each turbine shall be calculated by the end of the subsequent month using the emission factor(based on permitted hourly emission limit divided by design rate of turbine (339 mmBtu/hr)), the monthly natural gas consumption and the higher heating value of the fuel(see Condition 1.10)in the equation provided Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 9 in Condition 1.3.1. Monthly emissions from each turbine shall be used in a twelve-month rolling total to monitor compliance with the annual limitations. Each month a new twelve month total shall be calculated using the previous twelve months data. b. The natural gas used as fuel shall meet the sulfur limit in Condition 1.9. 1.4.2 Sulfur Dioxide(SO2)emissions from each turbine shall not exceed 0.35 Ibs/MMBtu,on a 3-hr rolling average(Colorado Regulation No. 1,Section VI.B.4.c.(ii)and V I.B.2). In the absence of credible evidence to the contrary, compliance with the SO2 limitations is presumed provided the natural gas used as fuel meets the sulfur content requirement in Condition 1.9. 1.5 Nitrogen Oxide(NOx)emissions shall not exceed the following: 1.5.1 Nitrogen Oxide Emissions from each turbine shall not exceed the above limitations (Colorado Construction Permits 87WE113-1 and-2,as modified under the provisions of Section I, Condition 1.3 to remove the hourly limitation). Compliance with the annual limitation shall be monitored using the continuous parametric monitoring system and compliance algorithm specified in Condition 1.8. Hourly emissions predicted by the algorithm from each turbine shall be summed to determine monthly emissions by the end of the subsequent month. Monthly emissions shall be used in a rolling twelve-month rolling total to monitor compliance with the annual limitation.

Any hours that exceed the limitation shall be reported on the excess emission report required by Condition 4.3. 1.6.2 The emission factor listed above(based on permitted hourly emission limit divided by design rate of turbine(339 mmBtu/hr))shall be used to calculate emissions. Monthly emissions shall be calculated by the end of the subsequent month using the above emission factor, the monthly natural gas consumption and the higher heating value of the gas(see Condition 1.10)in the equation provided in Condition 1.3.1. Monthly emissions from each turbine shall be used in a twelve-month rolling total to monitor compliance with the annual limitations. Each month a new twelve month total shall be calculated using the previous twelve months data. If a reference method test is conducted under the provisions of Condition 1.6.3, and the results of the testing show that either the NOx or CO emission rates/factors are greater than the emission rates/factors listed above, the permittee shall apply for a modification to this permit to reflect, at a minimum,the higher emission rates/factors within 60 days of the completion of the reference method test. 1.6.3 Portable Monitoring shall be conducted quarterly in accordance with the provisions in Condition 2 of this permit. 1.6.4 A performance test shall be conducted in accordance with the provisions in Condition 3 of this permit. 1.7 Natural gas consumption for each turbine shall not exceed the limitations stated above (Colorado Construction Permits 87WE113-1 and-2).

The Btu content used in emission calculations shall be based on the lowest gross heating value of the fuel. 1.11 Regulation No.6,Part A,Subpart A.General Provisions applies as follows: 1.11.1 No article,machine,equipment or process shall be used to conceal an emission which would otherwise constitute a violation of an applicable standard. Such concealment includes,but is not limited to,the use of gaseous diluents to achieve compliance with an opacity standard or with a standard which is based on the concentration of a pollutant in the gasses discharged to the atmosphere (40 CFR Part 60 Subpart A § 60.12). 1.11.2 At all times, including periods of startup, shutdown, and malfunction owners and operators shall to the extent practicable, maintain and operate any affected facility including associated air pollution control equipment in a manner consistent with good air pollution control practice for minimizing emissions. Determination of whether acceptable operating and maintenance procedures are being used will be based on information available to the Division which may include, but is not limited to monitoring results, opacity observations, review of operating and maintenance Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 12 procedures,and inspection of the source(Colorado Construction Permits 113-1 and-2 and 40 CFR Subpart A§60.11(d)). 1.12 The turbines are subject to the following opacity requirements: 1.12.1 Except as provided for in Condition 1.12.2 below, no owner or operator of a source shall allow or cause the emission into the atmosphere of any air pollutant which is in excess of 20% opacity (Colorado Construction Permits 87WE113-1 and —2 and Colorado Regulation No. 1, Section II.A.I). This opacity standard applies to each turbine. 1.12.2 No owner or operator of a source shall allow or cause to be emitted into the atmosphere any air pollutant resulting from the building of a new fire,cleaning of fire boxes, soot blowing, start-up, process modifications, or adjustment or occasional cleaning of control equipment which is in excess of 30% opacity for a period or periods aggregating more than six(6)minutes in any sixty(60) consecutive minutes (Colorado Regulation No. 1, Section II.A.4). This opacity standard applies to each turbine. 1.12.3 State-Only Requirement: No owner or operator may discharge, or cause the discharge into the atmosphere of any particulate matter which is greater than 20% opacity (Colorado Regulation No. 6, Part B, Section 11.C.3). This opacity standard applies to each turbine. This opacity standard applies at all times except during periods of startup, shutdown and malfunction (40 CFR Part 60 Subpart A § 60.11(c), as adopted by reference in Colorado Regulation No.6,Part B, Section I.A). Note that this opacity requirement is more stringent than the opacity requirement in Condition 1.12.2 during periods of building of a new fire, cleaning of fire boxes, soot blowing, process modifications and adjustment or occasional cleaning of control equipment. In the absence of evidence to the contrary,compliance with the above opacity requirements shall be presumed since only natural gas is permitted to be used as fuel for these turbines. 2. Portable Monitoring Requirements(6/1/06 version) Emission measurements of nitrogen oxides (NOx) and carbon monoxide (CO) shall be conducted quarterly using a portable flue gas analyzer. At least one calendar month shall separate the quarterly tests. Note that if the engine is operated for less than 100 hrs in any quarterly period, then the portable monitoring requirements do not apply. All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol (ver March 2006 or newer) as found on the Division's website at: http://www.cdphe.state.co.us/ap/down/portanalyzeproto.pdf Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 13 Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual or short term emission limit, the results of the tests shall be converted to a lb/hr basis and multiplied by the allowable operating hours in the month or year(whichever applies) in order to monitor compliance. If a source is not limited in its hours of operation the test results will be multiplied by the maximum number of hours in the month or year(8760),whichever applies. If the portable analyzer results indicate compliance with both the NOx and CO emission limitations, in the absence of credible evidence to the contrary,the source may certify that the engine is in compliance with both the NOx and CO emission limitations for the relevant time period. Subject to the provisions of C.R.S.25-7-123.1 and in the absence of credible evidence to the contrary,if the portable analyzer results fail to demonstrate compliance with either the NOx or CO emission limitations,the engine will be considered to be out of compliance from the date of the portable analyzer test until a portable analyzer test indicates compliance with both the NOx and CO emission limitations or until the engine is taken offline. For comparison with the emission rates/factors, the emission rates/factors determined by the portable analyzer tests and approved by the Division shall be converted to the same units as the emission rates/factors in the permit. If the portable analyzer tests shows that either the NOx or CO emission rates/factors are greater than the relevant ones set forth in the permit, and in the absence of subsequent testing results to the contrary(as approved by the Division),the permittee shall apply for a modification to this permit to reflect, at a minimum, the higher emission rate/factor within 60 days of the completion of the test. Results of all tests conducted shall be kept on site and made available to the Division upon request. 3. Performance Test Requirements Performance testing shall be performed every five (5) years to monitor compliance with the NOx and CO emission limitations in Conditions 1.5.1, 1.5.2 and 1.6. Performance testing shall be conducted in accordance with the provisions of 40 CFR Part 60 Subpart GG § 60.335 for NOx and Method 10 (40 CFR Part 60 Appendix A)for CO or other test methods or procedures acceptable to the Division. Note that the previous performance tests for these units were conducted on April 23,2008. A stack testing protocol shall be submitted for Division approval at least thirty(30)calendar days prior to any performance of the test required under this condition. No stack test required herein shall be performed without prior written approval of the protocol by the Division. The Division reserves the right to witness the test. In order to facilitate the Division's ability to make plans to witness the test, notice of the date(s)for the stack test shall be submitted to the Division at least thirty(30)calendar days prior to the test. The Division may for good cause shown,waive this thirty(30)day notice requirement. In instances when a scheduling conflict is presented, the Division shall immediately contact the permittee in order to explore the possibility of making modifications to the stack test schedule. The required number of copies of the compliance test results shall be submitted to the Division within forty- five(45)calendar days of the completion of the test unless a longer period is approved by the Division.

Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT • Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 25 b. Emission Monitoring Requirements The Division may require owners or operators of stationary air pollution sources to install,maintain,and use instrumentation to monitor and record emission data as a basis for periodic reports to the Division. c. Performance Testing The owner or operator of any air pollution source shall,upon request of the Division,conduct performance test(s) and furnish the Division a written report of the results of such test(s)in order to determine compliance with applicable emission control regulations. Performance test(s)shall be conducted and the data reduced in accordance with the applicable reference test methods unless the Division: (i) specifies or approves,in specific cases,the use of a test method with minor changes in methodology; (ii) approves the use of an equivalent method; (iii) approves the use of an alternative method the results of which the Division has determined to be adequate for indicating where a specific source is in compliance;or (iv) waives the requirement for performance test(s)because the owner or operator of a source has demonstrated by other means to the Division's satisfaction that the affected facility is in compliance with the standard. Nothing in this paragraph shall be construed to abrogate the Commission's or Division's authority to require testing under the Colorado Revised Statutes,Title 25,Article 7,and pursuant to regulations promulgated by the Commission. Compliance test(s)shall be conducted under such conditions as the Division shall specify to the plant operator based on representative performance of the affected facility.The owner or operator shall make available to the Division such records as may be necessary to determine the conditions of the performance test(s).Operations during period of startup,shutdown,and malfunction shall not constitute representative conditions of performance test(s)unless otherwise specified in the applicable standard. The owner or operator of an affected facility shall provide the Division thirty days prior notice of the performance test to afford the Division the opportunity to have an observer present.The Division may waive the thirty day notice requirement provided that arrangements satisfactory to the Division are made for earlier testing. The owner or operator of an affected facility shall provide,or cause to be provided,performance testing facilities as follows: (i) Sampling ports adequate for test methods applicable to such facility; (ii) Safe sampling platform(s); (in) Safe access to sampling platform(s);and (iv) Utilities for sampling and testing equipment.

Operating Permit Number:95OP W E001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 26 Nothing in this section shall abrogate the Division's authority to conduct its own performance test(s)if so warranted. d. Affirmative Defense Provision for Excess Emissions during Malfunctions Note that until such time as the U.S. EPA approves this provision into the Colorado State Implementation Plan (SIP),it shall be enforceable only by the State. An affirmative defense to a claim of violation under these regulations is provided to owners and operators for civil penalty actions for excess emissions during periods of malfunction. To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement,the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of evidence that: (i) The excess emissions were caused by a sudden,unavoidable breakdown of equipment,or a sudden, unavoidable failure of a process to operate in the normal or usual manner,beyond the reasonable control of the owner or operator; (ii) The excess emissions did not stem from any activity or event that could have reasonably been foreseen and avoided,or planned for,and could not have been avoided by better operation and maintenance practices; (iii) Repairs were made as expeditiously as possible when the applicable emission limitations were being exceeded; (iv) The amount and duration of the excess emissions(including any bypass)were minimized to the maximum extent practicable during periods of such emissions; (v) All reasonably possible steps were taken to minimize the impact of the excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation(if at all possible), (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed,contemporaneous operating logs or other relevant evidence; (viii) The excess emissions were not part of a recurring pattern indicative of inadequate design,operation,or maintenance; (ix) At all times,the facility was operated in a manner consistent with good practices for minimizing emissions. This section is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator,and shall not constitute an additional applicable requirement,and (x) During the period of excess emissions,there were no exceedances of the relevant ambient air quality standards established in the Commissions'Regulations that could be attributed to the emitting source. The owner or operator of the facility experiencing excess emissions during a malfunction shall notify the division verbally as soon as possible,but no later than noon of the Division's next working day, and shall submit written notification following the initial occurrence of the excess emissions by the end of the source's next reporting period. The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief The Affirmative Defense Provision does not apply to failures to meet federally promulgated performance standards or emission limits,including,but not limited to,new source performance standards and national emission standards for hazardous air pollutants.The affirmative defense provision does not apply to state implementation plan(sip) limits or permit limits that have been set taking into account potential emissions during malfunctions,including,but not necessarily limited to,certain limits with 30-day or longer averaging times,limits that indicate they apply during malfunctions,and limits that indicate they apply at all times or without exception. Operating Permit Number:95OPWE00I First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 27 e. Circumvention Clause A person shall not build,erect,install,or use any article,machine,equipment,condition,or any contrivance,the use of which,without resulting in a reduction in the total release of air pollutants to the atmosphere,reduces or conceals an emission which would otherwise constitute a violation of this regulation. No person shall circumvent this regulation by using more openings than is considered normal practice by the industry or activity in question. f Compliance Certifications For the purpose of submitting compliance certifications or establishing whether or not a person has violated or is in violation of any standard in the Colorado State Implementation Plan,nothing in the Colorado State Implementation Plan shall preclude the use,including the exclusive use,of any credible evidence or information,relevant to whether a source would have been in compliance with applicable requirements if the appropriate performance or compliance test or procedure had been performed.Evidence that has the effect of making any relevant standard or permit term more stringent shall not be credible for proving a violation of the standard or permit term. When compliance or non-compliance is demonstrated by a test or procedure provided by permit or other applicable requirement,the owner or operator shall be presumed to be in compliance or non-compliance unless other relevant credible evidence overcomes that presumption. g. Affirmative Defense Provision for Excess Emissions During Startup and Shutdown An affirmative defense is provided to owners and operators for civil penalty actions for excess emissions during periods of startup and shutdown. To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement, the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of the evidence that: (i) The periods of excess emissions that occurred during startup and shutdown were short and infrequent and could not have been prevented through careful planning and design; (ii) The excess emissions were not part of a recurring pattern indicative of inadequate design,operation or maintenance; (iii) If the excess emissions were caused by a bypass(an intentional diversion of control equipment),then the bypass was unavoidable to prevent loss of life,personal injury,or severe property damage; (iv) The frequency and duration of operation in startup and shutdown periods were minimized to the maximum extent practicable; (v) All possible steps were taken to minimize the impact of excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation(if at all possible); (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed,contemporaneous operating logs or other relevant evidence;and, (viii) At all times,the facility was operated in a manner consistent with good practices for minimizing emissions. This subparagraph is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator,and shall not constitute an additional applicable requirement. The owner or operator of the facility experiencing excess emissions during startup and shutdown shall notify the Division verbally as soon as possible,but no later than two(2)hours after the start of the next working day,and shall submit written quarterly notification following the initial occurrence of the excess emissions.The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief Operating Permit Number:95OP W E001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Power and Electric LLC Colorado Operating Permit Permit#95OPWE001 Page 28 The Affirmative Defense Provision does not apply to State Implementation Plan provisions or other requirements that derive from new source performance standards or national emissions standards for hazardous air pollutants,or any other federally enforceable performance standard or emission limit with an averaging time greater than twenty- four hours. In addition,an affirmative defense cannot be used by a single source or small group of sources where the excess emissions have the potential to cause an exceedance of the ambient air quality standards or Prevention of Significant Deterioration(PSD)increments. In making any determination whether a source established an affirmative defense,the Division shall consider the information within the notification required above and any other information the Division deems necessary,which may include,but is not limited to,physical inspection of the facility and review of documentation pertaining to the maintenance and operation of process and air pollution control equipment. 4. Compliance Requirements Regulation No.3 5 CCR 1001-5,Part C.§§III.C.9.,V.C.11 &16.d.and§25-7-122.1(2) C.R.S. a. The permittee must comply with all conditions of the Operating Permit.

If a conviction of any person under this paragraph is for a violation committed after a first conviction of such person under this paragraph,the maximum punishment shall be doubled with respect to both the fine and imprisonment. The permittee must comply with all conditions of this operating permit. Any permit noncompliance constitutes a violation of the Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification;or for denial of a permit renewal application. The Part 70 Operating Permit program requires three types of reports to be filed for all permits. All required reports must be certified by a responsible official. Report#1:Monitoring Deviation Report(due at least every six months) For purposes of this operating permit, the Division is requiring that the monitoring reports are due every six months unless otherwise noted in the permit. All instances of deviations from permit monitoring requirements must be clearly identified in such reports. For purposes of this operating permit,monitoring means any condition determined by observation,by data from any monitoring protocol, or by any other monitoring which is required by the permit as well as the recordkeeping associated with that monitoring. This would include, for example, fuel use or process rate monitoring,fuel analyses.and operational or control device parameter monitoring. Report#2:Permit Deviation Report(must be reported"promptly") In addition to the monitoring requirements set forth in the permits as discussed above, each and every requirement of the permit is subject to deviation reporting. The reports must address deviations from permit requirements, including those attributable to malfunctions as defined in this Appendix, the probable cause of Operating Permit Number:95OPWE00I First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 2 such deviations, and any corrective actions or preventive measures taken. All deviations from any term or condition of the permit are required to be summarized or referenced in the annual compliance certification. For purposes of this operating permit,"malfunction"shall refer to both emergency conditions and malfunctions. Additional discussion on these conditions is provided later in this Appendix. For purposes of this operating permit, the Division is requiring that the permit deviation reports are due as set forth in General Condition 21. Where the underlying applicable requirement contains a definition of prompt or otherwise specifies a time frame for reporting deviations, that definition or time frame shall govern. For example,quarterly Excess Emission Reports required by an NSPS or Regulation No. I,Section IV. In addition to the monitoring deviations discussed above, included in the meaning of deviation for the purposes of this operating permit are any of the following: (1) A situation where emissions exceed an emission limitation or standard contained in the permit; (2) A situation where process or control device parameter values demonstrate that an emission limitation or standard contained in the permit has not been met; (3) A situation in which observations or data collected demonstrates noncompliance with an emission limitation or standard or any work practice or operating condition required by the permit;or, (4) A situation in which an excursion or exceedance as defined in 40CFR Part 64(the Compliance Assurance Monitoring(CAM)Rule)has occurred.(only if the emission point is subject to CAM) For reporting purposes,the Division has combined the Monitoring Deviation Report with the Permit Deviation Report. All deviations shall be reported using the following codes: 1=Standard: When the requirement is an emission limit or standard 2=Process: When the requirement is a production/process limit 3=Monitor: When the requirement is monitoring 4=Test: When the requirement is testing 5=Maintenance: When required maintenance is not performed 6=Record: When the requirement is recordkeeping 7=Report: When the requirement is reporting B=CAM: A situation in which an excursion or exceedance as defined in 40CFR Part 64 (the Compliance Assurance Monitoring(CAM)Rule)has occurred. 9=Other: When the deviation is not covered by any of the above categories Report#3:Compliance Certification(annually,as defined in the permit) Submission of compliance certifications with terms and conditions in the permit,including emission limitations, standards,or work practices,is required not less than annually. Compliance Certifications are intended to state the compliance status of each requirement of the permit over the certification period. They must be based,at a minimum,on the testing and monitoring methods specified in the Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT • Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 3 permit that were conducted during the relevant time period. In addition,if the owner or operator knows of other material information(i.e. information beyond required monitoring that has been specifically assessed in relation to how the information potentially affects compliance status),that information must be identified and addressed in the compliance certification. The compliance certification must include the following: • The identification of each term or condition of the permit that is the basis of the certification; • Whether or not the method(s)used by the owner or operator for determining the compliance status with each permit term and condition during the certification period was the method(s) specified in the permit. Such methods and other means shall include,at a minimum,the methods and means required in the permit. If necessary,the owner or operator also shall identify any other material information that must be included in the certification to comply with section 113(c)(2)of the Federal Clean Air Act,which prohibits knowingly making a false certification or omitting material information; • The status of compliance with the terms and conditions of the permit,and whether compliance was continuous or intermittent. The certification shall identify each deviation and take it into account in the compliance certification. Note that not all deviations are considered violations.' • • Such other facts as the Division may require,consistent with the applicable requirements to which the source is subject,to determine the compliance status of the source. The Certification shall also identify as possible exceptions to compliance any periods during which compliance is required and in which an excursion or exceedance as defined under 40 CFR Part 64 (the Compliance Assurance Monitoring(CAM)Rule)has occurred.(only for emission points subject to CAM) Note the requirement that the certification shall identify each deviation and take it into account in the compliance certification.Previously submitted deviation reports, including the deviation report submitted at the time of the annual certification,may be referenced in the compliance certification. Startup,Shutdown,Malfunctions and Emergencies Understanding the application of Startup, Shutdown,Malfunctions and Emergency Provisions,is very important in both the deviation reports and the annual compliance certifications. Startup,Shutdown,and Malfunctions Please note that exceedances of some New Source Performance Standards(NSPS) and Maximum Achievable Control Technology (MACT) standards that occur during Startup, Shutdown or Malfunctions may not be considered to be non-compliance since emission limits or standards often do not apply unless specifically stated in the NSPS. Such exceedances must,however,be reported as excess emissions per the NSPS/MACT rules and would still be noted in the deviation report. In regard to compliance certifications, the permittee should be ' For example,given the various emissions limitations and monitoring requirements to which a source may be subject, a deviation from one requirement may not be a deviation under another requirement which recognizes an exception and/or special circumstances relating to that same event. Operating Permit Number:95OPWE001 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 4 confident of the information related to those deviations when making compliance determinations since they are subject to Division review. The concepts of Startup, Shutdown and Malfunctions also exist for Best Available Control Technology(PACT)sources,but are not applied in the same fashion as for NSPS and MACT sources. Emergency Provisions Under the Emergency provisions of Part 70 certain operational conditions may act as an affirmative defense against enforcement action if they are properly reported. DEFINITIONS Malfunction (NSPS) means any sudden, infrequent, and not reasonably preventable failure of air pollution control equipment, process equipment, or a process to operate in a normal or usual manner. Failures that are caused in part by poor maintenance or careless operation are not malfunctions. Malfunction (SIP) means any sudden and unavoidable failure of air pollution control equipment or process equipment or unintended failure of a process to operate in a normal or usual manner. Failures that are primarily caused by poor maintenance, careless operation, or any other preventable upset condition or preventable equipment breakdown shall not be considered malfunctions. Emergency means any situation arising from sudden and reasonably unforeseeable events beyond the control of the source, including acts of God, which situation requires immediate corrective action to restore normal operation, and that causes the source to exceed a technology-based emission limitation under the permit, due to unavoidable increases in emissions attributable to the emergency. An emergency shall not include noncompliance to the extent caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation,or operator error.

Please review and submit any comments you may have concerning the modified draft operating permit. Following our review of your comments, we will send the draft permit out for a 30-day Public Comment period and then to EPA for their 45-day review period. The regulations also require that the applicant receive written notice of their right to a formal hearing before the Colorado Air Quality Control Commission at the same time that the Public Comment packet goes out. You will receive a separate letter containing that information. This draft renewal permit contains the modifications that you requested in your renewal application received on August 10, 2009. The permit was also revised to be more consistent with recently issued permits, correct errors, omissions and discrepancies identified during inspections and/or review of the renewal application and incorporate EPA comments made on other operating permits for similar sources. The changes are summarized in the technical review document for the renewal permit. While you are reviewing this permit, please be aware of the following: 1. Since the original issuance of this permit, EPA has promulgated National Emission Standards for Hazardous Air Pollutant Emissions (NESHAP) for reciprocating internal combustion engines (RICE) located at area sources and Standards of Performance (NSPS) for both compression ignition and spark ignition engines: These requirements apply to both new and existing engines engines and apply to any size engine, many of which could otherwise be considered insignificant activities. Therefore please address the following issues related to these requirements: a.) Existing Engines. The insignificant activity list in your current permit indicates that there is a stand-by diesel generator and a diesel fire pump. Revisions to the RICE MACT were published on March 3, 2010 which apply to existing (commenced construction or reconstruction before June 12, 2006) compression ignition engines (all sizes) located at area sources and therefore, this engine is subject to the RICE MACT. Under the "catch-all" provisions in Colorado Regulation No. 3, Part C, Section II.E, sources that are subject to any federal or state applicable requirement such as a MACT standard cannot be considered an insignificant activity. As a result, these engines have been removed from the insignificant Mr. Richard Recor, Thermo Power and Electric, LLC August 4, 2010 Draft Renewal Operating Permit Page 2 activity list in Appendix A of the permit and are now included in Section II of the permit. Please provide the make, model, serial number and hourly fuel or heat input rate (e.g., gal/hr or mmBtu/hr) for these engines. b.) New Engines. Please indicate whether you have any engines that would meet the following requirements: Requirements Applicability Date Engine Type/Size 40 CFR Part 63 Subpart ZZZZ Constructed and/or Both Compression Ignition and reconstructed after 6/12/06 Spark Ignition, all sizes 40 CFR Part 60 Subpart IIII Construction commenced Compression ignition, all sizes (engine ordered) after 7/11/05, engine manufactured after 4/1/06. 40 CFR Part 60 Subpart JJJJ Construction commenced Spark Ignition, all sizes (engine ordered) after 6/12/06, engine manufactured after 7/1/07* *7/1/07 is the earliest manufactured date for which NSPS requirements apply, the manufactured date varies depending on size and type of engine. 2. EPA promulgated National Emission Standards for Hazardous Air Pollutants for Paint Stripping and Miscellaneous Surface Coating Operations at Area Sources (40 CFR Part 63 Subpart HHHHHH) on January 9, 2008. Since the Thermo Power and Electric, Inc. — Greeley facility is not a major source of hazardous air pollutant (HAP) emissions, these rules potentially apply. The Division believes that any spray coating of motor vehicles and mobile equipment and spray application of coatings that contain target HAPS that may occur at this facility would meet the definition of facility maintenance and would therefore, not be subject to the requirements in 40 CFR Part 63 Subpart HHHHHH. However, we cannot determine whether any paint stripping activities at this facility would be subject to these requirements. Please indicate whether any paint stripping chemicals used at your facility include methylene chloride. We would like you to review this permit and respond to the items identified above by September 8, 2010. Feel free to call me at (303) 692-3267 if you have any further questions.
